Promising Quantum Computing Stocks To Add to Your Watchlist - March 18th

Key Points

• MarketBeat's screener flags IonQ (IONQ), D‑Wave Quantum (QBTS), and Quantum Computing Inc. (QUBT) as the top quantum computing stocks by recent dollar trading volume.
• The companies have distinct offerings: IonQ provides cloud access to its general‑purpose quantum systems via AWS/Azure/GCP, D‑Wave sells Advantage hardware plus Ocean software and Leap cloud access, and Quantum Computing Inc. focuses on photonics‑based Dirac EQC machines, quantum random number generators, and quantum authentication solutions.
• Quantum stocks are a nascent, high‑potential but high‑risk sector—characterized by long development timelines, technical uncertainty, and elevated volatility—so they're typically treated as speculative, long‑horizon or diversified tech holdings.

IonQ, D-Wave Quantum, and Quantum Computing are the three Quantum Computing stocks to watch today, according to MarketBeat's stock screener tool. Quantum computing stocks are shares of publicly traded companies whose primary business or significant operations involve developing, manufacturing, or supporting quantum computing technologies—such as quantum hardware, software, algorithms, materials, or related infrastructure and services. For investors, these equities provide exposure to a nascent, high‑potential but high‑risk sector with long development timelines, technical uncertainty, and typically elevated volatility, so they are often treated as speculative, long‑horizon holdings or components of a diversified technology allocation. These companies had the highest dollar trading volume of any Quantum Computing stocks within the last several days.
