Nvidia Quantum AI Model Triggers Rally Across Global Quantum Stocks

Gate News message, April 15 — Quantum computing stocks surged globally after Nvidia released a new open-source AI package designed for quantum systems late Tuesday in Asia. The Ising model family, announced on April 14, is built to address quantum error correction and calibration—two major challenges in the industry. Nvidia's new tools can execute the decoding step for quantum error correction up to 2.5 times faster while delivering three times better accuracy, according to the company.

In Asian markets, the rally was immediate and substantial. South Korean stocks Axgate and ICTK briefly surged enough to hit the daily 30% ceiling. GuoChuang Software and QuantumCTek in China jumped more than 8%, while Japan's Fixstars also climbed 8%. By Wednesday, the buying momentum spread to the United States: D-Wave Quantum was up 10.3%, IonQ gained 13.3%, and Rigetti Computing climbed 8.9%. A separate uptick in risk appetite from revived US-Iran peace talks provided additional tailwinds for the sector.

Nvidia's Ising family comprises two main components. Ising Calibration is a vision-language model that automates continuous calibration, cutting the process from days to hours. Ising Decoding, built as a 3D convolutional neural network, comes in two versions—one optimized for speed and one for accuracy. Nvidia said the tools are already being deployed by Atom Computing, IonQ, IQM Quantum Computers, and Fermi National Accelerator Laboratory for Calibration, while Cornell University, Sandia National Laboratories, and the University of Chicago are using Ising Decoding.

Market research firm Stratistics predicts the global quantum computing market will grow from approximately $1.7 billion to over $11 billion by 2030. Europe is expected to see the fastest advancement over the next decade, driven by rising patent activity and efforts to commercialize quantum research. Leading players in the space include Accenture, Amazon Web Services, D-Wave, Fujitsu, Google, IBM, Intel, Microsoft, Rigetti, and Zapata Computing.
