IonQ Surges 11% as NVIDIA Research Center Deal Follows Error-Decoder Breakthrough; D-Wave Climbs 5%, Rigetti Rises 4%

IonQ (IONQ) shares rose 5% after announcing a quantum computing breakthrough and a collaboration with Nvidia (NVDA) to install its Superion 256 quantum computer at Nvidia's research center. The partnership will focus on financial modeling, portfolio optimization, and drug discovery. IonQ also reported a single CPU error detection and correction breakthrough, removing a bottleneck in fault-tolerant quantum computing.

IonQ's shares rose 11% after announcing a breakthrough in real-time quantum error correction, using a standard CPU. The development addresses a key challenge in quantum computing, but full fault-tolerant systems remain a future goal. Investors will watch for scaling and commercialization progress.

IonQ (IONQ) stock rose 4.9% after announcing a real-time quantum error correction decoder and a partnership with NVIDIA. The company's Superion 256 quantum computer will be deployed at NVIDIA's research center. IonQ's shares are up 327.5% over 5 years but down 8.5% year-to-date.

Nscale, a UK-based neocloud company, secured a $24M deal with ByteDance subsidiary Spring for access to 2,304 Nvidia B200 chips in Norway. The deal, revealed in Nscale's IPO filing, accounted for 73% of its 2025 revenue. Nscale also secured investments from Nvidia and Microsoft, with Nvidia committing over $2B in AI chip purchases. The deal raises regulatory and reputational risks due to U.S. export controls on China.

IonQ's shares rose over 5% after announcing a quantum computing breakthrough, the first real-time quantum error decoder. The company claims this advancement eliminates processing bottlenecks, allowing quantum systems to run continuously. IonQ has partnerships with AWS, Nvidia, and AstraZeneca, and recently acquired SkyWater Technologies, raising its full-year revenue guidance.

IonQ stock rose 13% after announcing a quantum error-correction breakthrough and a deal with Nvidia. Peers like Infleqtion and D-Wave also gained 7%.
