Briefings

Quantinuum and RIKEN expanded their partnership in November 2026 following the upgrade of the Reimei quantum computer to System Model H2. The collaboration focuses on quantum-AI hybrid supercomputing for electronics, energy, and life sciences, with plans to develop a fault-tolerant 'Made with Japan' quantum computer and explore connecting quantum computers to AI data centers in Japan.

Key points

• Quantinuum and RIKEN announced an expanded partnership in November 2026 to advance quantum-AI hybrid supercomputing in Japan.
• The Reimei quantum computer at RIKEN was upgraded to System Model H2, enabling research into complex quantum systems previously difficult to simulate.

Context

The partners combine quantum computing, supercomputing, and AI for research in electronics, energy, and life sciences. They are working with Japanese universities and suppliers toward a fault-tolerant quantum computer and exploring AI data center connections.

Limitations

Evidence covers only the partnership announcement and initial research projects on Reimei. Specific commercial timelines, full 'Made with Japan' development milestones, and the exact scope of the AI data center collaboration remain unconfirmed.
