Quantum computing stocks are extending their recent rebound Thursday as investors continue to digest a series of technical developments across the industry. IonQ (NYSE:IONQ) stock is up 4% to $44.08, while D-Wave Quantum (NYSE:QBTS) stock is gaining 3% to $17.23 and Rigetti Computing (NASDAQ:RGTI) stock is adding 2% to $16.28. The gains come as the […]
Today, Sept. 23, 2026, the trapped-ion quantum computing provider's decoder test and research-center collaboration kept commercialization progress in focus.
Cerebras is posting $510M in revenue with 76% growth and profitability, while Rigetti burns cash despite backing from Amazon and Microsoft.
IonQ just dropped two back-to-back announcements that sent its stock surging while the broader quantum ETF slipped, and the reason one company is pulling so far away from the pack reveals something important about where the real quantum race is being run.
IonQ Ignites Quantum Rally With Breakthrough in Real-Time Error Correction
IonQ (IONQ) shares rose 9.5% on Thursday, closing at $40.34 after six sessions that had mostly gone the other way. The reason on offer was research: quantum algorithms running inside mainstream engineering software, developed with Synopsys, sped up complex industrial design by up to 14.6%. That is genuine progress. It is also not a sale, and the price you pay for IonQ already assumes a great many sales.
Rigetti Computing (RGTI) sells quantum computing systems into a market its own management calls early, which makes the buy question hard to answer. You cannot lean on earnings, because Rigetti loses money, which leaves its price-to-earnings ratio meaningless. You can measure what you pay for each dollar of sales. Here is that walk, one step at a time.
IonQ's collaboration with NVIDIA on quantum optimization just sent the entire pure-play sector surging, but the market signal that actually reveals whether this is a real industry shift or just a speculative bet on one company's research is hiding in plain sight.
NVIDIA's new CUDA-Q Logical software links GPUs with quantum processors to tackle error correction, potentially benefiting IonQ, Rigetti, and D-Wave as hybrid computing advances.
The U.S. Commerce Department is investing up to $300 million for minority equity stakes in D-Wave, Rigetti, and Quantinuum, reinforcing balance sheets and reshaping quantum computing's valuation outlook.
Rigetti, D-Wave, and Quantinuum all just closed $100 million funding deals with the U.S. government.
Quantum Stocks Get a Major Boost as U.S. Commits $300 Million to Industry
The Commerce Department just took equity stakes in two quantum computing companies, and the fine print on that government ownership may matter more to long-term investors than today's share price pops.
The U.S. government is committing a combined $300 million to D-Wave Quantum, Rigetti Computing and Quantinuum.
IonQ is growing blisteringly fast.
A freshly listed quantum company just landed a multimillion-dollar NASA contract that sent its stock surging well past the broader quantum sector, and the reason it stands apart from IonQ, D-Wave, and Rigetti has everything to do with where it makes its money.
Quantum computing stocks are falling ten times harder than the NASDAQ 100 today, and the same revenue headlines that launched last week's rally may be the reason why.
Reddit just turned profitable with a 24.1% net margin, while Rigetti burns cash chasing quantum breakthroughs, a stark contrast in risk and reward.
Five pure-play quantum stocks surged between 7% and 10% on Friday with zero company announcements to explain the move, while the sector's biggest ETF barely budged. That gap between the fund and the names it supposedly holds tells you everything about what is really driving this trade.
Rigetti's Q2 revenues jumped 185.3% on Novera hardware sales, but widening losses and customer concentration keep the next system delivery in focus.
