Quantum Computing (NASDAQ:QUBT) shares are ripping higher in early Tuesday trading, up 26% to around $12.81 from a prior close of $10.18. The surge follows the company’s Q1 2026 earnings report, released after the close on May 11.
The move stands out across the pure-play quantum group. IonQ (NYSE:IONQ | IONQ Price Prediction) is basically flat at around $57, Rigetti Computing (NASDAQ:RGTI) is up 1% to $20.75, while D-Wave Quantum (NYSE:QBTS) is down about 5% to $22.80 after its own earnings hit the tape this morning.
So is Quantum Computing stock outperforming its peers? Today, clearly yes. Over the year so far, not quite.
Earnings Inflection Fuels the Surge
The Q1 2026 report delivered a major fundamental jolt. Quantum Computing posted EPS of -$0.02 versus a -$0.065 estimate, and revenue of $3.69 million, up 5,951% year over year year over year.
The revenue jump was powered by the $110 million all-cash acquisition of Luminar Semiconductor in February and a $5 million acquisition of NuCrypt in March. Quantum Computing CEO Yuping Huang said, “QCi made significant operational progress in the first quarter of 2026,” highlighting the company’s pivot toward integrated photonics manufacturing.
The company’s backlog reached roughly $16 million as of March 31, and Quantum Computing finished the quarter with $257.7 million in cash. The Dirac-3 commercial launch and expansion into photonics and edge AI hardware are the strategic anchors behind the move.
How QUBT Stacks Up Against IonQ, D-Wave, and Rigetti
Year to date through May 11, IonQ stock leads the pack at +27%, while Quantum Computing stock was essentially flat at -1%. Rigetti stock was down 7%, and D-Wave stock was down 8%.
The one-month performances tell a different story. IonQ shares are up 98%, D-Wave stock up 69%, Quantum Computing stock up 44%, and Rigetti stock up 40%. The sector has caught fire as all four reported earnings within a week.
IonQ set the tone last week with revenue of $64.67 million, up 755% year over year, and raised FY2026 guidance. D-Wave reported this morning, with revenue down 81% year over year due to a tough comp, although bookings surged to $33.4 million. Rigetti’s Monday report showed revenue of $4.4 million, nearly triple year-ago levels.
Sentiment, Short Interest, and Technology Approaches Diverge
Each name targets a different technology stack. Quantum Computing pursues photonic quantum computing, D-Wave operates quantum annealing systems, IonQ uses trapped-ion qubits, and Rigetti relies on superconducting qubits. High short interest at QUBT, paired with a positive catalyst and signs of institutional accumulation, has fueled active debate about a potential short squeeze.
Insider activity backs up the institutional confidence angle. Five Quantum Computing directors each purchased 22,123 shares at $6.78 on April 13, a coordinated buy well below current trading levels. Composite sentiment scores remain neutral, with QUBT at 54.36 and QBTS at 55.18.
What to Watch
Keep an eye on Quantum Computing stock through the close. The question is whether today’s gains hold and whether QUBT stock’s year-to-date number catches IonQ stock after this pop.
D-Wave’s first Investor Day on June 1 at the NYSE is the next anticipated sector-level catalyst. All four names carry meaningful execution risk, and single-day moves of this size can be characteristic of the group, in either direction.
