RIKEN's new hybrid platform leverages 540 NVIDIA Blackwell GPUs to create a massive classical simulation environment for quantum algorithms, bridging the gap between software development and physical quantum hardware. This infrastructure is critical for scaling quantum-HPC workflows by enabling high-bandwidth data exchange between classical supercomputers like Fugaku and emerging quantum processors. The deployment underscores the immediate reliance on advanced GPU clusters to simulate and optimize quantum systems before their full-scale realization.
540 NVIDIA GPUs power Japan’s research institute’s new quantum-HPC system

The RIKEN Center for Computational Science has finalized the system configuration for the “Supercomputer for Quantum-HPC Hybrid Platform,” designed to accelerate the integration of quantum computing and high-performance computing (HPC). The system consists of 135 compute nodes equipped with 540 NVIDIA Blackwell GPUs, interconnected via NVIDIA Quantum-X800 InfiniBand networking, delivering up to 3.2 terabits per second (Tbps).
RIKEN Center for Computational Science will deploy a new supercomputer powered by 540 NVIDIA Blackwell GPUs, establishing a hybrid platform for quantum and high-performance computing. The system achieves ultra-high-speed communication at 3.2 terabits per second using NVIDIA Quantum-X800 InfiniBand networking, and delivers computational performance exceeding 21 petaflops in FP64 and 5 exaflops in FP8. This installation, part of a project commissioned by NEDO, aims to accelerate the integration of quantum computing with existing resources like the Fugaku supercomputer and quantum computers ibm_kobe and Reimei. The system’s architecture prioritizes a simulation environment…
