Nvidia’s new open-source AI models for quantum computing have sent shares in companies like IonQ, D-Wave, Rigetti, and Quantum Computing sharply higher for a third straight session. Analysts say the tools could help the sector clear one of its biggest technical obstacles.
What happened with the stocks
Shares of IonQ and D-Wave Quantum each climbed around 15% on Wednesday, continuing gains that started when Nvidia made its announcement on Tuesday. Rigetti Computing rose about 10%. D-Wave Quantum and Quantum Computing each added around 6.4% in premarket trading Thursday, while Rigetti gained 4.5% and Infleqtion rose 4.2%.
IonQ, Inc., IONQ
The rally marks three straight sessions of gains for quantum computing stocks as a group.
What Nvidia announced
Nvidia released a set of open-source AI models called Ising on Tuesday. The suite includes two specific tools: Ising Calibration and Ising Decoder.
Ising Calibration uses AI to calibrate quantum processing units. Ising Decoder creates algorithms designed to correct errors that occur in quantum systems.
TD Cowen analyst Krish Sankar described the Ising models as a “key accelerant” for quantum commercialization. He said the tools tackle major challenges that have slowed the development of working quantum systems.
Sankar called quantum error correction, or QEC, a “fundamental” problem and the “next hurdle” every quantum company must clear to move forward commercially.
B. Riley Securities analyst Craig Ellis told MarketWatch that Nvidia had already released quantum tools called Cuda-Q and NVQLink in 2025. He had expected further developments in 2026. Ellis said the new Ising models for QEC calibration and error correction could enable more advanced AI workloads and become a major catalyst for quantum adoption over time.
Nvidia and the quantum computing sector have not always been on good terms. Early in 2025, Nvidia CEO Jensen Huang suggested that practical quantum computers could still be two decades away. That comment sent quantum stocks sharply lower at the time.
Since then, Nvidia has repositioned itself as a partner to the quantum industry rather than a skeptic.
The release of Cuda-Q and NVQLink in 2025, followed now by the Ising models, shows a clearer pattern of Nvidia investing in quantum tools. Analysts see that shift as a positive sign for the sector.
TD Cowen’s Sankar sees the Ising models as a step toward making quantum computing commercially viable. He pointed specifically to the calibration and error correction functions as solving real bottlenecks.
B. Riley’s Ellis had been watching for Nvidia to follow up its 2025 quantum tools with new releases in 2026. He believes the Ising models could drive adoption of quantum systems as a platform for more demanding AI tasks.
IonQ shares were up more than 20% and D-Wave was up over 22% as of the latest premarket data on Thursday.
