Quantinuum’s “Reimei” Quantum Computer Now Fully Operational at RIKEN, Ushering in a New Era of Hybrid Quantum High-Performance Computing

Quantinuum, the world’s largest integrated quantum computing company, and RIKEN, Japan’s largest comprehensive research institution, today announced the successful on-premises installation of Quantinuum’s “Reimei” quantum computer at RIKEN’s Wako campus in Saitama, Japan. 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 maximise the capabilities of Quantinuum’s quantum computers.

Named “Reimei,” which translates into “dawn” in Japanese, this powerful quantum computer symbolises 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 surpass the capabilities of traditional supercomputers—an exciting leap forward for scientific research.

This groundbreaking installation is part of an ambitious project commissioned by the New Energy and Industrial Technology Development Organisation (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 optimise operations within this innovative hybrid environment.

Additionally, Quantinuum will continue collaborating with RIKEN researchers to advance scientific discovery across various applications. The company will work with local suppliers to enhance the quantum supply chain and foster growth within the Japanese quantum computing ecosystem through customised, in-person workshops and tutorials.

Dr Mitsuhisa Sato, Division Director of the Quantum-HPC Hybrid Platform Division, RIKEN Center for Computational Science, said: “Reimei’s high-fidelity qubits and all-to-all connectivity will significantly enhance the research possibilities of our quantum-HPC hybrid platform. We are thrilled to explore new frontiers in scientific research on quantum-HPC hybrid applications by using the Quantinuum system with our Fugaku.”

Dr Rajeeb Hazra, President and CEO of Quantinuum, emphasised the significance of this milestone: “This installation represents a pivotal moment for our global strategy, marking the first on-site deployment of our quantum technology outside the U.S. We are eager to collaborate with RIKEN’s exceptional researchers, whose expertise will be instrumental in driving unprecedented scientific breakthroughs.”
