Quantum computing stocks have climbed as much as 50% this week after Nvidia $NVDA launched Ising, a family of open-source AI models designed to tackle two of the hardest engineering problems in the field: quantum error correction and processor calibration.
Shares of IonQ and D-Wave Quantum have both gained 50% over the course of the week, while Quantum Computing and Rigetti Computing have posted gains exceeding 20%.
Named after a mathematical model used to simplify the understanding of complex physical systems, Ising includes two main tools, Nvidia said. Ising Calibration is a vision language model that automates the continuous tuning of quantum processors, cutting the time required from days to hours. Ising Decoding uses a 3D convolutional neural network to perform real-time quantum error correction — delivering up to 2.5 times faster performance and three times higher accuracy than pyMatching, the current open-source industry standard.
Nvidia CEO Jensen Huang offered his view in a statement: “AI is essential to making quantum computing practical. With Ising, AI becomes the control plane — the operating system of quantum machines — transforming fragile qubits to scalable and reliable quantum-GPU systems.”
The models are available on GitHub, Hugging Face, and build.nvidia.com. Developers can also run them locally to protect proprietary data.
Adoption of the new tools spans a broad range of institutions. Ising Calibration is in use by IonQ, Atom Computing, Infleqtion, and…
