NVIDIA Ising is the world's first family of open AI models purpose-built for quantum computing infrastructure. Released on GitHub, Hugging Face, and build.nvidia.com, the suite tackles the two hardest engineering problems in practical quantum computing: processor calibration and error correction decoding. Ising Calibration is a 35B-parameter vision-language model trained on multi-modality qubit data. It automates the continuous, finicky process of tuning quantum processors — work that previously required highly specialized physicists and took days. Ising Decoding is a pair of 3D convolutional neural network models (optimized for either speed or accuracy) that handle real-time quantum error correction, running up to 2.5x faster and achieving 3x greater accuracy than pyMatching, the current open-source standard. As Jensen Huang framed it: "AI becomes the control plane — the operating system of quantum machines." Ising is already deployed at Harvard, Fermilab, Berkeley Lab, IonQ, IQM, Atom Computing, and a dozen other leading quantum institutions. With the quantum computing market projected to surpass $11 billion by 2030, Ising positions NVIDIA as the infrastructure layer for quantum-classical hybrid systems — not just GPU compute.

NVIDIA Ising is the world's first family of open-source quantum AI models, launched April 14, 2026 on World Quantum Day. It targets two of the most expensive bottlenecks in making quantum processors useful: calibration (tuning the QPU to operate correctly) and error correction (detecting and fixing quantum errors in real-time). Both are currently handled by hand or with classical algorithms that don't scale. Ising Calibration is a 35-billion-parameter vision-language model fine-tuned to read experimental measurements from a quantum processing unit and infer the precise adjustments needed to tune it, reducing calibration time from days to hours when wrapped in an agentic loop. Ising Decoding ships two 3D convolutional neural network variants (0.9M and 1.8M parameters) for surface-code quantum error correction — up to 2.5× faster and 3× more accurate than pyMatching, the current open-source standard decoder. All models are available on GitHub, Hugging Face, and build.nvidia.com, alongside training data, workflows, and NVIDIA NIM microservices for fine-tuning on custom QPU hardware. Early adopters include Fermi National Accelerator Laboratory, Harvard, Lawrence Berkeley National Lab, IQM Quantum Computers, and the UK National Physical Laboratory. For quantum startups working to make NISQ devices practically useful, Ising dramatically reduces the engineering burden that today consumes much of their engineering bandwidth.
Reviewer scorecard
“Open-sourcing calibration and decoding models on HuggingFace is a major unlock for academic quantum labs. What previously required a team of physicists can now be bootstrapped from a pretrained model. If you're in quantum research, this is essential tooling.”
“QPU calibration going from days to hours with an open model is the kind of infrastructure unlock that unblocks entire research teams. The NIM microservices for fine-tuning on custom hardware show NVIDIA actually thought about how this gets adopted. If you're in quantum, this is table stakes now.”
“Quantum computing 'breakthroughs' have been perpetually 5 years away for two decades. A 35B calibration model is impressive, but it doesn't solve the fundamental decoherence problem — and training your own Ising variant requires quantum hardware most researchers don't have.”
“A 35B calibration model that needs NVIDIA hardware to run efficiently is a funny definition of 'open.' The organizations already adopting this all have existing NVIDIA compute relationships. For a startup without H100s, the operational overhead of running Ising Calibration may exceed the time savings it provides.”
“NVIDIA is doing to quantum what it did to deep learning in 2012 — providing the infrastructure layer that makes the technology practically accessible. If quantum reaches fault-tolerance within this decade, Ising will be seen as the pivotal enabling toolkit.”
“Quantum computing's transition from research curiosity to engineering discipline has been blocked for years by the calibration and error correction problem. NVIDIA solving this with open models — and open training data — could compress the timeline to fault-tolerant quantum by half a decade. The implication for drug discovery, materials science, and cryptography is hard to overstate.”
“Too far from anything creators can use today — this is deep infrastructure for quantum labs and research institutions. The visualization tools for qubit data are fascinating but the audience is physicists, not designers.”
“This is highly technical infrastructure, but the narrative around quantum AI tools reaching open-source parity is creatively fascinating. For anyone building in the science communication or deep tech content space, the Ising launch is a compelling story about how AI is eating the most expensive parts of experimental physics.”
