A hybrid quantum-classical supercomputer dubbed Roquo has been installed at the Riken Center for Computational Science (R-CCS) in Kobe, Japan.. Named after Mount Rokko, the system was introduced as part of a JHPC-quantum project and commissioned by the New Energy and Industrial Technology Development Organization (NEDO), Japan’s largest public funding and management organization.. – Riken.
Giga Computing Technology was responsible for the design and manufacture of the compute nodes, while DataDirect Networks provided the high-speed file system. ScaleWorX oversaw the system integration.. Roquo provides 19.8 petaflops of compute performance and is among the first systems globally to adopt Nvidia’s GB200 NVL4, a configuration designed specifically for high-performance computing (HPC) applications..
Comprised of 135 compute nodes, totaling 540 Blackwell GPUs, interconnected by Nvidia Quantum-X800 InfiniBand networking, the supercomputer also contains Nvidia Quantum-X800 InfiniBand and Quantum-X800 switches. Roquo is connected via the SQC Interface to support the development of hybrid HPC-quantum computers, including the country’s most powerful supercomputer, Fugaku..
“The JHPC-quantum project aims to advance hybrid computing technologies that integrate quantum computers with HPC systems,” said Mitsuhisa Sato, director of the R-CCS Quantum-HPC Hybrid Platform Division. “In recent years, the integration of GPU-accelerated computing and AI technologies has attracted significant attention, and the deployment of this new GPU supercomputer comes at a particularly opportune time.
We expect that this system will contribute to further advances in quantum-HPC hybrid computing and enable the exploration of new application areas.”. More in HPC & Quantum. 27 Mar 2026.
