HPC SYSTEMS Provides FPGA Cluster Powered by IBEX Technology for RIKEN’s Quantum Error Correction Research

HPC SYSTEMS Inc. has developed and delivered a state-of-the-art, custom-engineered FPGA cluster system to RIKEN, one of Japan's leading research institutions. This powerful new system, featuring IBEX Technology’s IPAC-1000 acceleration cards, is designed to run scalable, high-performance algorithms for quantum error correction—a critical step toward building fault-tolerant quantum computers.
This initiative is a key part of Japan’s ambitious Moonshot R&D Program, which seeks to create the world's first fault-tolerant, general-purpose quantum computers.
The FPGA cluster supports large-scale, high-frequency circuit implementation and offers memory flexibility with both HBM and DDR for memory-intensive designs. Furthermore, the system is equipped with 400Gbps network ports for high-speed communication between FPGA units.
This strategic collaboration between RIKEN, IBEX Technology, and HPC SYSTEMS is expected to significantly advance the hardware infrastructure for quantum error correction, bringing the era of reliable quantum computing one step closer to reality.
