Arqit Quantum Inc is a cybersecurity technology company focused on delivering quantum-safe encryption solutions designed to protect sensitive data and communications against current and future threats. Leveraging principles of quantum mechanics, Arqit has developed a patented platform that generates encryption keys in the cloud and distributes them on demand to devices, networks and applications without the need for pre-shared secrets. This approach enables organizations to secure data in transit and at rest with a level of protection that classical cryptography alone cannot guarantee once large-scale quantum computers become available.
The company’s flagship offering, QuantumCloud, operates as an encryption-as-a-service solution that integrates with existing IT infrastructures, providing seamless key management and rapid deployment. Arqit also offers a suite of software development kits (SDKs) and application programming interfaces (APIs) that allow enterprises and government agencies to embed quantum-safe cryptography into their own systems. These products support a range of use cases, from securing satellite communications and critical national infrastructure to protecting financial transactions, automotive networks and IoT ecosystems.
Headquartered in London with offices in New York and Ottawa, Arqit serves a global customer base that includes defense organizations, telecommunications providers and Fortune 500 companies. The company has established strategic partnerships with leading industry players to extend its reach into North America, Europe and the Asia-Pacific region. By collaborating with government agencies and research institutions, Arqit aims to accelerate the adoption of quantum-secure communications across sectors where data integrity and confidentiality are paramount.
Founded in 2019 by Dr. David Williams and a team of cryptographers and physicists, Arqit Quantum has grown rapidly as quantum computing research has advanced. Under the leadership of Chairman Mark Newman and Chief Executive Officer Bill Chappell, the company has expanded its intellectual property portfolio and completed multiple successful trials of its technology in real-world environments. With a focus on innovation and rigorous security standards, Arqit continues to refine its platform to address evolving cyberthreats and to prepare organizations for the quantum era.
