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 research labs including Fermi National Accelerator Laboratory, Harvard's John A. Paulson School of Engineering and Applied Sciences, and Lawrence Berkeley National Laboratory's Advanced Quantum Testbed. Ising Decoding is being deployed by Sandia National Laboratories, the University of Chicago, and several other universities and startups.
The April 14 launch date was no coincidence: the day has carried the informal designation of World Quantum Day since 2021, when scientists around the world agreed to use it to raise public awareness of the technology. April 14 maps to 4.14, the opening digits of the Planck constant, one of quantum physics's foundational numerical values.
Even with the surge, the sector has struggled in 2026. D-Wave has shed roughly 20% of its value since January, and Rigetti is down about 15%,. Taken together, the biggest players in the space are valued at around $31 billion.
The broader quantum computing market is expected to surpass $11 billion by 2030, Nvidia said, citing analyst firm Resonance — growth that depends on continued progress in error correction and scalability, the two problems Ising is designed to address.
