Japan plans to deploy a 2,000 GPU supercomputer for quantum computing research.

Alongside the Nvidia H100s interconnected by Nvidia Quantum-2 InfiniBand, the ABCI-Q supercomputer is designed for integration with future quantum hardware.

The supercomputer follows the AI Bridging Cloud Infrastructure (ABCI) and ABCI 2.0 systems built at the University of Tokyo. The 2.0 supercomputer had a peak Linpack performance of 54.34 petaflops in Top500's latest listing.

Built by Fujitsu at the Global Research and Development center for Business by Quantum-AI Technology (G-QuAT) National Institute of Advanced Industrial Science and Technology (AIST), ABCI-Q is expected to be deployed early next year.

“Researchers need high-performance simulation to tackle the most difficult problems in quantum computing,” Tim Costa, director of HPC and quantum computing at Nvidia, said.

“CUDA-Q and the Nvidia H100 equip pioneers such as those at ABCI to make critical advances and speed the development of quantum-integrated supercomputing.”

CUDA-Q is Nvidia's open-source hybrid quantum computing platform that includes simulation tools and capabilities to program hybrid quantum-classical systems.
