Nvidia has launched the Nvidia quantum AI supercomputer known as ABCI-Q. It is located at the new Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT) in Japan. This system is now the world’s largest research-focused quantum AI supercomputer.
Developed with Japan’s National Institute of Advanced Industrial Science and Technology (AIST), ABCI-Q features 2,020 NVIDIA H100 GPUs. These GPUs connect through NVIDIA Quantum-2 InfiniBand, enabling high-speed performance and low latency.
Unlike previous systems, ABCI-Q supports large-scale quantum-GPU hybrid workloads. This integration brings together quantum hardware and traditional AI supercomputing. As a result, researchers can explore new frontiers in fields like healthcare, energy, and finance.
The system runs on CUDA-Q™, Nvidia’s open-source platform for hybrid computing. It manages both quantum and classical components in a single environment. Therefore, developers can orchestrate resources easily across different processors.
“Seamlessly coupling quantum hardware with AI supercomputing will accelerate realizing the promise of quantum computing for all,” said Tim Costa, senior director at Nvidia. He added that Nvidia’s work with AIST will advance quantum error correction and application development, which are vital for building scalable systems.
Additionally, ABCI-Q includes three different quantum processors. These are:
- A superconducting qubit processor from Fujitsu
- A neutral atom processor from QuEra
- A photonic quantum chip from OptQC
This diverse setup allows scientists to test hybrid workloads across various qubit types. As a result, the system offers unmatched flexibility in quantum research.
Nvidia quantum AI supercomputer ABCI-Q is more than just a high-performance machine. It’s a key platform for understanding the real-world challenges of quantum computing. Moreover, it helps bridge the gap between theoretical research and practical solutions.
According to Masahiro Horibe, deputy director of G-QuAT and AIST, the system empowers Japan’s researchers. “ABCI-Q will enable exploration of the core challenges quantum computing faces,” he said. “NVIDIA’s platform helps scientists build the stepping-stone systems we need to reach practical applications.”
Importantly, the combination of AI acceleration and quantum computing makes this a global milestone. Nvidia continues to lead not only in AI hardware but also in building platforms that drive future breakthroughs.
As global competition in quantum technology heats up, this launch reinforces Japan’s leadership in research. It also shows how public-private collaboration can push technological boundaries forward.
