Quantum Stocks Rally: RGTI, QUBT, IonQ Lead Double-Digit Rally on Speculation Buzz

Sep 19 - Quantum computing stocks gained ground on Friday, closing out a volatile week for the sector. Quantum Co. QMCO surged more than 28% in late-morning trading, while Quantum Computing Inc. ( QUBT) advanced over 22%. IonQ IONQ, Arqit Quantum ARQQ, and D-Wave Quantum QBTS also added more than 3%. Rigetti Computing RGTI climbed nearly 15% by midday.

No single catalyst explained the broad rally, though reports suggested the Trump administration may consider executive actions to speed up quantum security initiatives. The speculation added fuel to a market already energized by renewed investor interest in 2025.

Large technology companies have helped reinforce the momentum. Alphabet GOOGL, Amazon AMZN, Microsoft MSFT, and Nvidia NVDA have all expanded their quantum research efforts, increasing Wall Street's focus on the space.

Earlier in the week, IonQ joined Honeywell (HON) and The Electric Power Board of Chattanooga in a Department of Energy collaboration to explore quantum use cases in space. IonQ also disclosed plans to acquire Vector Atomic to broaden its capabilities in the quantum sector.

All told, the rally highlights how policy buzz, big-tech investment, and bold strategic moves are converging to keep quantum stocks firmly in the spotlight.
