As a reminder, today's program is being recorded. And now I'd like to introduce your host for today's program, Sabod Kulkarni, President and Chief Executive Officer. Please go ahead, sir.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Good afternoon, and thank you for participating in Rigetti's earnings conference call during the first quarter ended 03/31/2025. Joining me today is Jeff Bertelsen, our CFO, who will review our results in some detail following my overview. We will be pleased to answer your questions at the conclusion of our remarks. We would like to point out that this call and Rigetti's first quarter ended 03/31/2025 press release contain forward looking statements regarding current expectations, objectives and underlying assumptions regarding our outlook and future operating results. These forward looking statements are subject to a number of risks and uncertainties that could cause actual results to differ materially from those described and are discussed in more detail in our Form 10 ks for the year ended 12/31/2024, our Form 10 Q for the three months ended 03/31/2025, and other documents filed by the company from time to time with the Securities and Exchange Commission.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

These filings identify and address important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward looking statements. We urge you to review these discussions of risk factors. Today, I'm pleased to report on a number of new developments at Rigetti Computing. As previously disclosed, we have been selected to participate in DARPA's quantum benchmarking initiative. Rigetti will advance to stage a, a six month performance period focused on our utility scale quantum computer concept.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Our proposed concept to design and build a utility scale quantum computer combines our proprietary multi chip architecture with scalable quantum error correction or QEC codes. Our long long time partner and leader in QEC code technology, Riverlane, will collaborate with us on this project to help refine our proposed utility scale quantum computer concept and validate the underlying technology. I'm also very excited about our recent AFOSR award to further develop our breakthrough chip fabrication technology, alternating bias assisted annealing or ABAA. We will lead a $5,480,000 consortium consisting of Iowa State University, the Royal Melbourne Institute of Technology, the University of Connecticut, and Lawrence Livermore National Laboratory to develop a detailed understanding of how ABAA impacts a chip on a microscopic level, which aims to shed light on defects in superconducting qubits and open new avenues for understanding and mitigating them. We have also been awarded three Innovate UK Quantum Mission Pilot Awards to advance superconducting quantum computing.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We will collaborate with RiverName and the National Quantum Computing Center or NQCC superconducting circuits team to advance quantum error correction capabilities on superconducting quantum computers. The consortium will conduct ambitious QEC tests that advance state of the art metrics and demonstrate real time QEC capabilities, a requirement for universal fault tolerant quantum computing. As part of the project, we will also upgrade our existing quantum computer currently deployed at the NQCC. The upgrades will include deploying a larger 36 qubit quantum processing unit and integrating Rigetti's latest generation control system, enabling improved qubit control and a fully programmable low latency interface with RiverLane's QEC stack. We were also awarded two additional quantum missions pilot competition projects.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We will collaborate with CQC to integrate its digital chip based technology with our nine qubit Novera QPU hosted at the NQCC with the goal of identifying and understanding the key components needed for scalable QEC. We will also collaborate with TRAC, QRUZ, QControl, and Oxford IONIQs to create an open architecture quantum computing testbed and deliver an open specification for quantum workflows, creating a common interface between quantum software and hardware. On the technical update front, our joint paper with Harvard University, Massachusetts Institute of Technology, and University of Chicago, coherent control of a superconducting qubit using light has been published in Nature Physics. Quantower quantum computing will likely require 10,000 to a million physical qubits. Scaling these systems is challenging because they require bulky microwave components with high thermal loads that can quickly overwhelm the cooling power of a dilution refrigerator.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Optical signals have a considerably smaller footprint and negligible thermal conductivity. The team successfully demonstrated the integration of a hybrid microwave optical quantum transducer with a rigid fabricated superconducting qubit. This hybrid setup enables optical control of the qubit, removing the need for coax lines and provides a promising approach to scaling to higher qubit count systems. We also recently leveraged our new quantum optimization algorithm, quantum preconditioning, to address a power energy grid problem. Using a public dataset representing South Carolina's energy grid, the problem was to compute the maximum power section, a metric that informs on the health and power delivery capability of the energy network.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Using Rigetti's eighty four qubit Anka three system, quantum preconditioning was used to boost best in class classical optimizers. A relative advantage against the classical baseline was achieved along with a high solution accuracy, highlighting the potential for quantum preconditioning to achieve quantum utility for solving practical optimization problems. Finally, I'm pleased to report that Rigetti has closed its previously announced investment by Quanta Computer Inc. Related to our strategic collaboration agreement. In connection with the closing in late April, Ponta purchased approximately $35,000,000 worth of Rigetti common stock at roughly $11.59 per share.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Thank you. Jeff will now make a few remarks regarding our recent financial performance.

[Jeffrey Bertelsen, CFO at Rigetti Computing]

Thanks, Subot. Revenues in the first quarter of twenty twenty five were $1,500,000 compared to $3,100,000 in the first quarter of twenty twenty four. Renewal of the US National Quantum Initiative, sales to US and foreign governments, and Novera are all important to future sales. Gross margins in the first quarter of twenty twenty five came in at 30% compared to 49% in the first quarter of twenty twenty four. The lower gross margins on a year over year basis were due to ongoing revenues from our contract with The UK's NQCC to deliver a 24 cubic quantum system, which has a lower gross margin profile than most of our other revenue.

[Jeffrey Bertelsen, CFO at Rigetti Computing]

On the expense side, total OpEx in the first quarter of twenty twenty five was $22,100,000 compared to $18,100,000 in the same period of the prior year. The increase in total OpEx was due to annual salary increases, new hires, higher FICA taxes related to the vesting of RSUs and the increase in our stock price, and a reduction in the amount of engineering time used to deliver revenue. Higher stock compensation expenses for employee spot bonuses also contributed to the increase. Stock compensation expense for the first quarter of twenty twenty five was $4,200,000 compared to $3,000,000 for the first quarter of twenty twenty four. Our operating loss for the first quarter of twenty twenty five came in at $21,600,000 compared to $16,600,000 in the prior year period.

[Jeffrey Bertelsen, CFO at Rigetti Computing]

We recorded $42,600,000 of net income for the first quarter of twenty twenty five, compared to a net loss of $20,800,000 in the prior year period. Our net income for the first quarter of twenty twenty five was driven by the non cash changes in the fair value of our derivative warrant and earn out liabilities, which had a 62,100,000.0 favorable impact on net income for the quarter. Derivative warrant and earn out liabilities had a 4,200,000.0 unfavorable impact on our net loss for the first quarter of twenty twenty four. As of 04/30/2025, following the closing of the previously announced share purchase by Quanta Computer, cash, cash equivalents and available for sale investments totaled $237,700,000 Thank you. We would now be happy to answer your questions.

[Operator]

Certainly. And our first question for today comes from the line of Brian Kinstlinger from Alliance Global Partners. Your question please.

[Brian Kinstlinger, MD, Director of Research & Head of Technology Research at Alliance Global Partners]

Great. Thanks so much for taking my question. In the past you highlighted that chip tiling is expected to get Rigetti to 36 cubits at midyear and over 100 by the end of twenty twenty five at Fidelity rates of 99.75%. I'm curious, we're just a month and a half away from mid year. Can you speak to the progress you're making on tiling?

[Brian Kinstlinger, MD, Director of Research & Head of Technology Research at Alliance Global Partners]

And do you think that these timeframes are still reasonable?

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Sure. Thanks, Brian, for your question. Indeed, deploying chiplets is a very critical part of our strategy because we believe that's the real good way to scale up a number of qubits as we go forward using monolithic dye that we have used in the past along with many of our peers, works obviously, and we have systems that are deployed that are doing well, but we see a significant challenge in squeezing more qubits on a single monolithic die, which is why we deployed the chiplet approach. In the past, we have deployed two chiplets in a system. And then last year, we announced that we have done that with two nine qubit chiplets at a much higher fidelity level.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We feel pretty confident that the chiplet approach with the four nine qubit chiplets sometime middle of this year and taking it over a hundred qubits by the end of this year is going to work. All the data looks promising. We feel optimistic that we should be able to disclose our results as time goes on. I don't have anything specific to report. I mean, as we have said in the past, our two attempts with two chiplets have worked.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

All the fundamental data suggest that our attempts at four and eventually multiple chiplets is going to work. This is not just important for Rigetti, but for it's frankly important for the whole industry, because this is the only way we see how you scale up the qubit counts. Some of their companies in superconducting have tried to do larger monolithic chips and they haven't worked quite well. And frankly, the other modalities are significantly behind the superconducting modality in terms of qubit count, so we really don't see them coming to hundreds and thousands of qubits. So we really believe that chiplets is the right way to scale up superconducting qubits and and show a path towards the fault tolerant quantum computing systems.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Hope that answers your question, Brian.

[Brian Kinstlinger, MD, Director of Research & Head of Technology Research at Alliance Global Partners]

For sure. Absolutely. I have one follow-up and then I'll get back in the queue. I know there were some hearings recently regarding the NQI Reauthorization Act. I'm curious what you're hearing in regards to the new funding bill and you know, how you think about when it might get approved or, you know, what you're hearing.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Yes, certainly the inquiry authorization act seems to have bipartisan support in our government and there are multiple versions of the bills that have been floated both in the House and Senate. As of today, it hasn't passed yet. And even after it passes, there is always a time for the money to be appropriated. So we are talking at least a couple months from now before we actually start seeing money flow out of the NQI reauthorization bill. Many of us, we for sure, but many quantum computing companies are eagerly awaiting for the NQI reauthorization to pass.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We are pretty optimistic based

[Brian Kinstlinger, MD, Director of Research & Head of Technology Research at Alliance Global Partners]

Great. Thank you.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Thanks, Brian.

[Operator]

Thank you. And our next question comes from the line of David Williams from The Benchmark Company. Your question, please.

[David Williams, Equity Research Analyst at The Benchmark Company LLC]

Hey. Good afternoon, gentlemen. Thanks for letting me ask a question here. I I guess maybe first on the DARPA contract that you won. Can you give a little more information about that?

[David Williams, Equity Research Analyst at The Benchmark Company LLC]

I know this is phase one, but how do you expect that to to proceed? And what should we be looking for in terms of milestones?

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Sure. Thanks for the question, David. I mean, DARPA Quantum Benchmarking Initiative project is an extremely critical project for the country. Its goal is to build utility scale quantum computing by in the next seven years. Really, I mean, we have used words like fault tolerant quantum computing in the past and essentially it means the same thing, something that really shows value over the cost is the way Arapah defines it.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Our view is to deliver a system like that, you need tens of thousands, if not hundreds of thousands of physical qubits. You need better than 99.9% median two qubit gate fidelity. And you need faster than ten nanoseconds gate speed, and you need real time error correction code. So once again, more than 10,000 qubits, more than 99.9% median two qubit gate fidelity, faster than ten nanosecond gate speed, and real time error correction. Once you get those kinds of numbers, we believe one will achieve DARPA's milestone of utility scale quantum computing or what we have commonly referred to in the past as fault tolerant quantum computing.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Extremely important project for the country. We are proud to be selected as the group for selected for phase a. In a way, it's a vetting process. Our understanding is more than a hundred companies applied for that. DARPA has chosen 15 companies within the superconducting camp.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Along with us, it's basically IBM and HP, I believe. And there are some other modalities DARPA has also chosen. This is called phase a over the next six months, DARPA is going to announce the winners of the next phase, phase b. We expect the number to go down significantly from 15. The actual number will depend on the progress that various companies accomplish.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We don't know exactly what other companies are doing. From our standpoint, we know exactly what our plan is and it comes back to what we have publicly stated. We want to demonstrate chiplets, we want to demonstrate higher fidelity than what we have done already. Our current system, as you are probably aware, is at 84 qubit with 99 or 99.5% median two qubit gate fidelity depending on what kind of gates you use. We want to bump that number over 100 qubit, but using chiplets and bump the fidelity up to 99.5 to 99.7% again, depending on what kind of gates you use.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So we know what we have to do to get from phase a to phase b. We assume other companies will be doing their part as well. DARPA has said they will narrow the list down in phase b and ultimately in phase c. Eventually, in a year, year and a half, maybe two years from now, we expect one or maybe two companies are left in that process. Our goal clearly is to be in that final group.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

That's where the real substantial award will be awarded to build a final quantum computer. So in a way, our view is DARPA vetting process is a nice validation of our technology. We are proud to be part of the group that has been selected for 15. We certainly want to be part of the next group and the one beyond that. Hope that answers your question.

[David Williams, Equity Research Analyst at The Benchmark Company LLC]

It does. Thanks so much. No. It's exciting to be a part of that initial group. Are there revenues that are associated with with each one of those phases as you're making contributions towards those specs?

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Yeah. There are some revenues, and we have disclosed that the phase a is a $1,000,000 award. We view it in a very strategic sense. I mean, as we have discussed before, our focus as a company is on R and D and technology milestones. Some of these government projects do come with sizable awards.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

In this case, phase A is relatively small. Phase b, the number will increase significantly, and phase c, certainly, the number will increase quite a bit. So our view right now is this is we we view this as a very strategic kind of a project, not really from a monetary standpoint.

[David Williams, Equity Research Analyst at The Benchmark Company LLC]

Sure. Okay. Very good. And and then just maybe, from, an interest standpoint from maybe customers that are looking, to acquire the processor itself. I know in the past, it seemed like that pipeline or that interest level had picked up quite a bit.

[David Williams, Equity Research Analyst at The Benchmark Company LLC]

Any thoughts or colors on just maybe how you're seeing customers now? And would you say that the interest is increasing? Or have you seen a leveling off? Anything in in terms just kind of trying to size that that interest level that you're seeing on the QPU side? Thank you.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So sure. Thanks for the question. I mean, overall quantum computing continues to be in an R and D mode. Our view is that we are still very much in the stage of developing quantum computers. We are still four to five years away from what we call quantum advantage, which is when you need at least a thousand qubits, at least 99.8% to qubit gate fidelity and some real time error correction.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Until then, it's going to be primarily R and D, primarily driven by government contracts, academic researchers. So there, by definition, those kinds of sales are one off sales, they are lumpy in nature. I wouldn't really interpret sales from any quantum computing company honestly right now to in serious way. This is all r and d going on right now. Really, the goal should be to get a quantum computer to quantum advantage, and that's really when commercial sales and sales in general make start making sense.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

And we are talking at least three years from now, maybe four to five years from now. So until then, this is primarily an r and d kind of a situation. Having said that, I mean, there are government national labs and academic researchers who are interested in using quantum computers, whether they are on the cloud through AWS or Azure, or actually getting on premise quantum computers as we have done with Novera for academic researchers. Interest is definitely there. A lot of this organization depend on DOE funding, which is primarily the NQI reauthorization.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So there is a lack of funding in general for academic institutions right now until the NQI passes and is appropriated. DOD funding situation is a little better, and that's where we have seen some of the contracts like the AFO, SR contract or the DARPA contract. But a lot of academic institutions and DOE labs certainly depend on the NQI reauthorization. So, even though the interest is there for Nuvera and on premise QPUs, I would say lack of funding from the US government is certainly holding that interest converting to orders. But again, I'll highlight that our view is we are still very much in R and D.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We focus on technology milestones. This one off sales from government contracts, as exciting as they could be, that's not a real metric that we think should be watched at this point. Hope that answers your question.

[David Williams, Equity Research Analyst at The Benchmark Company LLC]

Yes, sir. It does. Thank you so much for the help, sir. Appreciate it.

[Operator]

Thank you. And our next question comes from the line of Quinn Bolton from Needham and Company. Your question, please.

[Quinn Bolton, Senior Analyst at Needham & Company]

Hi, Subodh and Jeff. Maybe Subodh, just a quick

[Quinn Bolton, Senior Analyst at Needham & Company]

clarification on the your answer to the NQI reauthorization. Did you do you have a sense that that could be signed within the next couple of months? I think you said it would probably take a couple of months after the bill is signed before the funds would start to flow, but I wasn't sure if you had given thoughts on when that may pass.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Well, thanks for the question, Quinn. I mean, it was supposed to pass almost a year ago, but still hasn't happened yet, And this is having bipartisan support. So, in a way, is frustrating to see the slow progress of the NQRE authorization bill through the House and Senate right now. As I said, there have been multiple versions of the bills that have been floated between the House and Senate. There seems to be bipartisan support as recently as four days ago, I believe there was a hearing on the House floor.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Again, we saw bipartisan support for the bill. President Trump has indicated that he supports quantum computing. So no reason to believe it won't pass, but as of today, it hasn't passed. Normally, for a bill like this, appropriations process does take a few weeks, four to six weeks is the normal number that gets used. So once the bill is passed, it still takes a month to two months for money to start flowing to the DOE labs and academic institutions.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

And that's where really we get funded from. So it will still be a while before we see the benefits of NQLD authorization materially translate into our financials.

[Quinn Bolton, Senior Analyst at Needham & Company]

Understood. My first question was regarding the new award, The UK Innovate award, I think it was with NQCC where you're to upgrade to the 36 qubit QPU with enhanced control. Do you have a timeframe on sort of how long that project runs? Is that something that you could deliver that 36 QPU this year? And I guess related question, mentioned the gross margin

[Quinn Bolton, Senior Analyst at Needham & Company]

for

[Quinn Bolton, Senior Analyst at Needham & Company]

the NQCC 24 bit QPU has been below average. Would you expect the 36 qubit QPU to also carry lower gross margins? Or could that be revenue that comes in at better margins than the initial 24 qubit QPU

[Quinn Bolton, Senior Analyst at Needham & Company]

sale?

[Subodh Kulkarni, President & CEO at Rigetti Computing]

In general, I'll take the second part first. In general, NQCC margins are lower than the average because it's primarily a cost sharing model that the UK government has. We do that despite the low margin as reported because it's strategically very important. Right now, the UK government has clearly chosen us as the technology provider for the conducting site. When you visit the NQCC Centre in Harwell, which is close to Oxford, UK, you will see that the only working supercomputer, superconducting quantum computer is Rigattis right now.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

And the UK government is putting a lot of faith in us in allowing them to develop the ecosystem using our technology. So we absolutely want to continue supporting that, even if it's a cost sharing model, which needs to lower gross margin percent on our financials, because it's strategically very important to us to be a key player in The UK quantum ecosystem. Regarding the first part of your question, we have disclosed in the past that even though we brought up the 24 qubit system at the NQCC, the actual chip we use is an 84 qubit chip in that system. So, it's only really a question of cables and wires that we have to upgrade if you really wanted to just upgrade the 24 qubit to 36 qubit. So, that's one easier path, if you will, to get The UK upgraded to 36 qubit.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

But what they really would like to do and we also would like to do is once we demonstrate the chiplet approach with four by nine qubit at a higher fidelity, the 99.5% for the generic gate, and 99.7 for the F SIM type gate. We would like to bring that latest and best technology to The UK. So, ideally, we want to demonstrate that first in California in our facilities, And once we have demonstrated that, then we would like to bring it to The UK, which would mean roughly second half of this year is when we would upgrade them to the chiplet approach and 36 qubit. But we could certainly upgrade them 36 qubit sooner if they really want it right now using the existing Ankara Three chip, which is an 84 qubit chip. So hope that answers your question.

[Quinn Bolton, Senior Analyst at Needham & Company]

Got it. So it sounds

[Quinn Bolton, Senior Analyst at Needham & Company]

like you have two two paths.

[Quinn Bolton, Senior Analyst at Needham & Company]

You could you could either upgrade the existing QPU since it's 84 qubits or you could bring the tile 36 qubit once you've demonstrated that in the second half of the year. I think that's pretty clear. The other question I had and maybe this is just a longer term technical question, you know, to get to utility scale computing you gave us sort of four key criteria. One of them was increasing the gate speeds. And I think today your gate speeds are in the tens of nanoseconds range and you want to get that down to ten nanoseconds.

[Quinn Bolton, Senior Analyst at Needham & Company]

What how do you do that? Is that kind of smaller qubits, smaller circuitry? Is it just optimizing the control signals? Like, what's how do you improve the gate speed on the QPUs? Thank you.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Great question, Quinn. I mean, let's talk a little bit about gate speeds first. So yes, you are right. Our AMCA three system that is deployed on AWS and Azure right now, which is the 84 qubit system, has a gate speed of about 70 right now. In general, if you look at all the superconducting gate based modality quantum computing companies, our gate speeds are in the 50 to 100 nanosecond range.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

The numbers vary a little bit depending on the exact technology, but they are in that range. There are many knobs that can improve gate speeds. And we before I move, get into what we are going to do next, let's just talk a little bit about the importance of gate speed, I mean, because that often gets forgotten. I mean, when we compare superconducting modality to trapped ion or pure atom modalities, the gate speeds for those modalities are in the hundreds of microseconds, so they are like 1,000 to 10,000 times slower than the superconducting gate based modality. I'll repeat that again, that 10,000 to 10,000 times slower than superconducting gate based modality.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

I didn't realize that matters. I mean, I've never seen any customer who has said they want their computer to be 10,000 times slower. So it absolutely is critical that trapped ion and pure atom moralities increase their gait speed, so to be competitive with superconducting. And honestly, see a tremendous amount of scientific challenges ahead of them. Now coming back to superconducting side, the number one thing to improve our gate speed, which was over a hundred nanosecond, was to move from fixed coupler technology to tunable coupler technology.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We did that with AMCA two, and then we improved that further with AMCA three. That's what got us in the 50 to a hundred nanosecond range, and we noticed that some of our peer companies in superconducting gate based modality have done similar work. After that, what we are looking at is the type of that we use has a big impact on gate speed, whether it's the control Z, whether it's the ISWAP, whether it's the FCM, whether it's something else. The type of gates matter because that's what really determines how fast you can do it. But there are other important variables to how good the coupling is between the qubits and that gets into the geometry and other design parts of the chip.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So, there are many other knobs out there that help us with gate speed. Our goal certainly is to continue to improve it, because that's such a critical metric that we have to monitor. Hope that answers your question.

[Quinn Bolton, Senior Analyst at Needham & Company]

Yeah. That was great. Thank you, Shiva.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Thanks, Quinn.

[Operator]

Thank you. And our next question comes from the line of Krish Sankar from TD Cowen. Your question please.

[Analyst]

Hi, this is Steven calling on behalf of Krish. Thanks so much for taking my questions. The first one is for Subodh. I had a couple of questions on the ABA development consortium. So that first of all, that 5,480,000.00, I guess grants reward for yourself and your partners.

[Analyst]

Can you talk about how that award amount is to be divided amongst the partners in that consortium, first of all? And then I had a follow-up on that.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So, yeah, we don't want to get into the details of exactly how the award gets divided at that level, Chris. We will get majority of that award out of the various partners. But we did I mean, in the big scheme of things, it's honestly not that important exactly what the number is. It's such a critical strategic project for us and and the industry. So we don't want to minimize the importance of it by getting into nickels and dimes, to be honest.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

ABA is a very critical technology to scale up superconducting gate based quantum computing. The initial results that we showed last year have been very promising. The DOD, the Air Force of AFOSR organization wants us to accelerate commercialization of that technology because it's so important. Some very prestigious labs, as you can see, Lawrence Livermore National Lab, AIMS Lab from Iowa, and a couple of other universities are part of that because they have some key faculty members who are doing excellent research in related areas. So we think it's a very important strategic award for the whole industry and certainly for us.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So I don't want to get into the breakdown, if that's okay with you.

[Analyst]

Yeah, that's fair. Not a problem. And the other question I had related to ABA is, I guess, a technology perspective, again, I understand that it helps to that technology progress helps to improve the quality of the qubits, but just dig down a little further into the details. Does ADA help to, I guess increase the consistency of the behavior across different gates or is this helping a different vector of the performance of the superconducting gates?

[Subodh Kulkarni, President & CEO at Rigetti Computing]

In general, APA is we are using it right now for what we say frequency targeting. When we have when we build QPS, there's a range of frequencies they respond to, and we obviously want to have precise control over which frequency they respond to. Because once we can target them at a certain frequency, helps us define coupling and other interactions. So, ABA helps essentially our process control of the qubit manufacturing process, gives us a precise control on the frequency. And then we have papers out there that you can look at where we show that the distribution spread and when we without ABA and with ABA and with ABA, the usually get the spread reduced by improved by almost 10x or more.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

It's a really important way to control the frequency targeting of the qubit and get better process control of the qubit.

[Analyst]

It. Understood.

[Analyst]

And just also for my final question, I had one for for Jeff on OpEx. Jeff, just wondering after Q1's '20 '2 million dollars in OpEx, I understand there's a number of, guess, seasonal increases and bonuses baked in there. Just wondering for the June and onwards, is like a high teens million OpEx run rate still the right number to be thinking about? Or is this low 20s level the more appropriate number we should be modeling for? Thank you.

[Jeffrey Bertelsen, CFO at Rigetti Computing]

Yeah, I mean, I

[Jeffrey Bertelsen, CFO at Rigetti Computing]

think certainly this quarter, as I had mentioned, there were a couple of factors that caused OpEx to be a little bit high in Q1. FICA tax was one. There were some spot bonuses that impacted stock compensation expense. So going forward, hopefully, we'll see a little bit of a reduction.

[Analyst]

Okay, thank you.

[Operator]

Thank you. And our next question comes from the line of Richard Shannon from Craig Hallum. Your question please.

[Richard Shannon, Senior Research Analyst at Craig-Hallum Capital Group LLC]

Well, hi, Subodh and Jeff, thanks for taking my questions. Subodh, maybe I'll ask you a question on one of the things you mentioned as well as in the press release here about optical signaling. I guess maybe if you could talk about the importance of that and then also let me get a sense of when you think this enters the roadmap. Are we getting close to that timeframe or is this still early stage R and D?

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Nice question, Richard. Thank you. Indeed, optical signaling is a very important element of our roadmap and for that matter, the whole industry's roadmap. And the main reason for that is right now we all use coax cables in the dilution refrigerator. That's what sends the signals in.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

That's what gets the signals out. And obviously, it works at a hundred cubic level and we think it will even work up to several hundred qubits. But then beyond that, you literally start running out of space in a given dilution refrigerator system. We are experimenting with flex cables along with many other players in the industry, and we certainly think flex cables have a role to play. So a few hundred qubits to maybe a thousand or a few thousand qubits, we think we will switch from coax cables to flex cables.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Beyond that though, and we still need something beyond because even flex cables are not good enough to take us to the tens of thousands of qubits that we need to deliver this point over in quantum computing system or the infinity scale quantum computing system that DARPA is asking for. And that's really where we start we have started experimenting with optical cables. Converting microwave signal that which is what we use to control our qubits to optical signals has been done in literature before. There have been many papers in the past. Where we came in along with our partners like QFOX, and more recently, Harvard University at MIT, is showing that you can do it in actually a fiber optic cable, not just open air optics, if you will.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

And that's extremely important because that makes it a lot more practicable in real life. So now we are envisioning a little bit of fiber optic cable going in a dilution refrigerator and the fiber optic cable coming out of the dilution refrigerator. And the physical size requirement for fiber optic is significantly smaller than even a flex cable. And that is a tremendous advantage, not only from a physical space standpoint, but also from the thermal load, which converts into the cool down times and so on. So, what are we would love to switch over from coax cables to flex cables to fiber optics as soon as possible.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

From a practical standpoint, we think for the right now it's coax for the next year, two years, maybe even three years, we will be in the co flex cable regime, and somewhere in the three to four year before we start getting into the thousands and tens of thousands of physical qubits is when fiber optics will start entering our road map, and for that matter, the industry's road map. So we are definitely a pioneer in this space. We are leading a lot of the work. But once we prove it, I'm sure the rest of the industry will be looking at, something like this as well. Hope that answers your question.

[Richard Shannon, Senior Research Analyst at Craig-Hallum Capital Group LLC]

That that answer completely, Subodh. Thanks for that. My other question is, I'm not sure if it's for Subodh or Jeff here, but, when we look collectively at the NQCC revenue opportunity as well as the Air Force, I forget what the acronym is there, I think the $1,000,000 there, what do we think about in terms of the timeframe over which that'll be recognized? Maybe even if you could elaborate how much we might see recognized this year.

[Jeffrey Bertelsen, CFO at Rigetti Computing]

Yeah, guess I'll take

[Jeffrey Bertelsen, CFO at Rigetti Computing]

Okay, yeah. So the NQCC opportunity, let me take that one first, that runs really for a year. So I would expect that revenue to be essentially booked over time over the course of the next year. In terms of the Air Force opportunity contract, I mean, I think when we look at that contract, we're looking at roughly on the magnitude of over the course of the upcoming year, it's roughly going to probably be about $1,000,000 It's a three year contract in total. But in terms of next year, it's probably about $1,000,000

[Richard Shannon, Senior Research Analyst at Craig-Hallum Capital Group LLC]

Okay. Thanks for that color. That's all for me.

[Operator]

Thank And

our next question comes from the line of Craig Ellis from B. Riley Securities. Your question, please.

[Craig Ellis, Director of Research at B Riley Financial]

Yeah, thanks for taking the question and apologies if RDS hopped in a little late. So, but I wanted to start off just by going back to the DARPA stage A and congratulations on making it to that level. But the question is this, what specifically are they looking for in stage A? What boxes does Ragheti need to check to move on to the next phase of that program after stage A?

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So, Craig, the goal for the DARPA project is utility scale quantum computing in the next six to seven years. They have three stages, stage A, stage B, stage C, we have been selected for stage We believe to get to stage B, we have to execute the roadmap that we have publicly disclosed. So, that would mean demonstrating the chiplet approach, the first of four by nine qubit at a very high fidelity, like 99.5% for generic gates and 99.7 for f sim type gates. Assuming we do that by the middle of this year as we have publicly disclosed is our plan and assuming we are on track to demonstrate more than hundred qubits using the chiplet approach at similar fidelity levels, we believe that should be enough to get us into phase b. Because clearly, that's a very leadership situation in the superconducting camp to be demonstrating chiplet at more than a hundred qubit at 99.5, median two qubit gig fidelity.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

We really don't know what other companies' roadmaps exactly are and what they are committing to DARPA, so we cannot have we cannot comment on that. But as far as we are concerned, we think as long as we execute the roadmap that we have publicly disclosed, that should enable us to participate in phase b.

[Craig Ellis, Director of Research at B Riley Financial]

Excellent. Thank you. And then the follow-up question is related to the Quanta relationship. So, a quarter ago, we announced the relationship that was very significant. This quarter, we announced that the investment of $35,000,000 has closed, so that's further tightened and solidified the relationship.

[Craig Ellis, Director of Research at B Riley Financial]

The question is this, as investors and analysts look at what the next steps are for that relationship, can you help us with some things that would be reasonable milestones from here through the end of this year and then some things that would be on the 2026 roadmap to help us understand where that relationship can go for the company? Thank you.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

Thanks for the question. Quanta is indeed a very strategic partner for us going forward. So as we disclosed, we did get the $35,000,000 for roughly 3,000,000 shares that they got at $11.59 But more importantly, if you look at our announcement when we made it a couple months ago, we said that they have committed to investing $250,000,000 over the next five years in the non GPU hardware portion of the stack. So, non GPU hardware portion of the stack includes things like control systems, the dilution refrigerator, the cables, the chassis, and many other components. And that's really what quanta is good at.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

I mean, if you look at what role do they play in the CPU, GPU, server ecosystem, that's really what they do. And they are obviously a global leader in that space. So they are bringing their expertise and their high volume, low cost manufacturing expertise, obviously, in addition to that. And they are going to be essentially investing on in a non PPO hardware portion of the stack for our technology. Basically, that mean what that means is we have to invest less in that part of the stack, which normally we would have to do on our own.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

So it certainly helps us not invest R and D dollar in that. So that does help us enable that helps enable our focus in the QPU portion of the stack, which is basically the chip design, chip fabrication and the immediate hardware that goes around it. So, long term, we can see how it's going to play. Right now, we are working very closely with them. We are essentially teaching them how to become our contract manufacturer or ODM partner, if you will, and how to build our control system that works with our stack.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

By this time next year, I'm pretty confident that they will be doing bulk of the control systems r and d, and they would have started picking up other hardware portions of the stack along with it, reducing the pressure of us to do r and d in those areas. So hope that answers your question of how we envision the partnership going forward.

[Craig Ellis, Director of Research at B Riley Financial]

It does and it would seem to mean that either a R and D at current levels would refocus to something that's much tighter and more core to scaling up cubic quality and cubic count or potentially r and d would go down, but it gives you a lot of degrees of freedom with how you allocate r and d dollars given the narrow focus that you'll be able to have at that point.

[Subodh Kulkarni, President & CEO at Rigetti Computing]

That's correct. I mean, it's primarily to help accelerate our timeline to market. Quanto, obviously, is a terrific partner ODM company. They will certainly help us on the high volume manufacturing side as business really becomes commercial type business in the next three to four years.

[Craig Ellis, Director of Research at B Riley Financial]

Thanks, Subhan.
