Tokyo, Japan, February 12th, 2025 — Quantinuum, the world’s largest integrated quantum computing company, and RIKEN, Japan’s largest comprehensive research institution, today announced the successful on-premise installation of Quantinuum’s “Reimei” quantum computer at RIKEN’s... RIKEN has designed, prepared, and delivered a world-class facility for the trapped-ion quantum computer, which will enable generations of high-performance quantum systems. This state-of-the-art machine is now fully operational, ushering in a new era of discovery and innovation. With its installation at RIKEN’s world-class facility, Japanese researchers now have direct, on-site access to Quantinuum’s cutting-edge quantum computing technology, renowned for being the highest performing systems in the world. Quantinuum’s hardware stands out as the only available system using a unique architecture that physically moves qubits, unlocking new tools and possibilities unavailable on other platforms. The exceptional performance and consistency of the system are supported by the stability of the facility's world-class environment, which is designed, built, and maintained to maximize the capabilities of Quantinuum's quantum computers.

Named “Reimei,” which translates into “dawn” in Japanese, this powerful quantum computer symbolizes the incredible potential of quantum technology and integrated hybrid computational platforms. The trapped-ion quantum computer by Quantinuum will work in harmony with RIKEN’s famed Japanese flagship supercomputer Fugaku, creating a cutting-edge quantum-HPC hybrid platform designed to tackle computations that surpasses the capabilities of traditional supercomputers—an... This groundbreaking installation is part of an ambitious project commissioned by the New Energy and Industrial Technology Development Organization (NEDO), a national research and development entity under Japan’s Ministry of Economy, Trade and Industry. Looking ahead, the next phase of this collaboration will focus on the integration of a quantum-HPC hybrid platform in 2025. Quantinuum is excited to team up with RIKEN and other partners to optimize operations within this innovative hybrid environment. Quantinuum and RIKEN have announced that the “Reimei” trapped-ion quantum computer is now fully operational at RIKEN’s Wako campus in Japan.

Installed in a world-class facility, Reimei provides Japanese researchers with direct access to Quantinuum’s high-performance quantum computing technology, known for its unique qubit movement architecture and high-fidelity operations. The deal was originally announced in January 2024 with a planned installation date of early 2025, which Quantinuum has met. The Reimei processor is based upon Quantinuum’s 20 qubit H1 design, but it also includes a unique feature set that supports advanced application and error correction research. Reimei will integrate with RIKEN’s Fugaku supercomputer to form a quantum-HPC hybrid platform designed for advanced computations beyond the reach of classical systems. This installation is part of a project commissioned by Japan’s New Energy and Industrial Technology Development Organization (NEDO), aiming to accelerate quantum research and applications. Quantinuum will also collaborate with RIKEN to advance quantum-HPC research and foster Japan’s quantum computing ecosystem.

This marks Quantinuum’s first on-premise deployment outside the U.S., reinforcing its global strategy and Japan’s commitment to quantum innovation.
