Fire Opal was integrated with the IBM Quantum System Two at RIKEN in Kobe, which sits next to Japan's Fugaku supercomputer. It is Q-CTRL's first on-premises deployment at a supercomputing centre, serving dozens of research groups in chemistry, machine learning and physics.

## Key facts

- Q-CTRL claims more than 1,000x better accuracy and efficiency (no independent figures given).
- Part of Japan's JHPC-quantum project, commissioned by NEDO under METI.
- Its second major Fire Opal deployment in Japan, after Keio University.
