Q-CTRL, a quantum infrastructure software company, and RIKEN, a national research institute in Japan, have announced the integration of Q-CTRL’s performance management software, Fire Opal, with RIKEN’s IBM Quantum System Two. The system is deployed within the RIKEN Center for Computational Science, which is co-located with Japan’s flagship supercomputer, Fugaku.
The integration is part of the JHPC-quantum project, commissioned by the New Energy and Industrial Technology Development Organization (NEDO), which aims to build a quantum-HPC integrated platform and expand computational domains. Fire Opal’s automated performance management and error-reduction technology are now available to users of the JHPC-quantum project, providing a reported improvement of more than 1,000× in both accuracy and efficiency.
The software enables users to run more efficient, accurate quantum circuits without requiring changes to their existing workflows, significantly reducing computational overhead. The integration supports dozens of research groups working on quantum chemistry, quantum machine learning, sample-based quantum diagonalization (SQD), and physics simulations.
Mitsuhisa Sato, Division Director of the Quantum-HPC Hybrid Platform Division at RIKEN, stated that the integration is a meaningful step forward in enabling scientific and industrial progress through their quantum-HPC integrated platform. Q-CTRL is positioning this as a tool that accelerates outcomes for R&D teams focused on achieving quantum advantage in critical applications.
