Top Quantum Computing Stocks To Keep An Eye On - December 28th

Key Points

• IonQ (IONQ), D-Wave Quantum (QBTS), and Quantum Computing Inc. (QUBT) are MarketBeat's top quantum computing stocks today, chosen for having the highest recent dollar trading volume among peers.
• Quantum stocks are typically speculative and high‑volatility, long‑horizon investments driven by technological uncertainty, heavy R&D spending, and nascent market adoption, making them more suitable as growth or diversification bets than stable income holdings.
• Product focuses differ: IonQ sells cloud access to its quantum machines via AWS/Azure/Google, D‑Wave offers the Advantage systems plus Ocean software and Leap cloud access, and Quantum Computing markets portable photonics EQC devices, quantum RNGs, and quantum authentication solutions.

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 publicly traded companies whose core business or significant operations involve developing, manufacturing, or commercializing quantum computers, quantum software and algorithms, enabling hardware (e.g., qubits, cryogenics, control electronics), or cloud/consulting services that provide access to quantum processing. For investors, these equities are typically speculative and high‑volatility plays with long time horizons due to technological uncertainty, heavy R&D spending, and nascent market adoption, so they are often considered growth or diversification bets rather than stable income or value investments. These companies had the highest dollar trading volume of any Quantum Computing stocks within the last several days.
