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 […]
IonQ appears to be the clear leader in one key area of quantum computing.
IonQ recently announced it will deploy its Superion 256 quantum computer on-premise at NVIDIA’s Accelerated Quantum Research Center, while also unveiling an end-to-end real-time quantum error correction decoder that runs on a single off-the-shelf CPU with minimal computational delay. Together, these advances highlight IonQ’s push to link scalable error-corrected quantum hardware directly with leading AI and GPU infrastructure, potentially simplifying future hybrid quantum-classical system...
Today, Sept. 23, 2026, the trapped-ion quantum computing provider's decoder test and research-center collaboration kept commercialization progress in focus.
IonQ stock rallies on landmark deal with Nvidia. But does that make IONQ shares worth buying today? Let’s find out!
Investors looking to participate in quantum computing stock upside with minimized single-stock risk might consider this ETF play.
IonQ said it would be the first on-premises quantum computing deployment at Nvidia’s Accelerated Quantum Research Center.
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.
The company says its decoder runs on a single standard CPU, removing a bottleneck that forced quantum computers to pause during error correction
The company says a single off-the-shelf CPU can now decode quantum errors in real time
IonQ Ignites Quantum Rally With Breakthrough in Real-Time Error Correction
Quantum computing is still in its early innings, but IonQ and IBM are already building the hardware and infrastructure that could power the next decade of growth.
IonQ looks primed to skyrocket in the next few years.
This expensive quantum computing stock isn't growing as fast as it seems.
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.
IBM Lands $1 Billion Quantum Award as IonQ Stock Rises on AI Breakthrough
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.
One operates in a crowded market and the other chases quantum's uncertain timeline.

IonQ is leading the accuracy segment of the quantum computing race.
Quantum computing is risky but can produce tremendous returns for early investors. IonQ investors understand the risk and may want to consider additional quantum stocks for more exposure.
Quantum Stocks Get a Major Boost as U.S. Commits $300 Million to Industry
New chips, a Bitcoin warning, and a huge guidance hike. IonQ packed a lot of news into one morning.
IonQ Unveils Superion 256 as Shares Jump on Higher Revenue Forecast
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.
Quantum computing may be a ways out, but it's not too early to position your portfolio to benefit.
