Quantinuum's Quantum Computer 'Reimei' Now Operational at RIKEN

On February 11, 2025, Quantinuum, the world's leading integrated quantum computing company, announced the successful operation of its cutting-edge quantum computer, 'Reimei', at RIKEN's state-of-the-art facilities in Wako, Saitama Prefecture, Japan. This significant milestone not only reinforces Quantinuum's position in the quantum computing landscape but also marks a pivotal moment for scientific research in Japan.

A New Dawn in Quantum Computing

The term 'Reimei', meaning 'dawn' in Japanese, encapsulates the transformative potential of the hybrid quantum computing landscape that this machine heralds. This system is equipped with advanced trapped-ion technology, which is recognized for its high fidelity and exceptional performance. With its unique architecture that allows physical movement of qubits, 'Reimei' opens up new realms of capabilities for researchers, distinguishing it from any other quantum computing platform currently available.

The technology installed at RIKEN provides unprecedented access to advanced quantum computing tools, enabling researchers to address complex scientific queries that supersede the capabilities of traditional supercomputers. This integration comes at a time when Japan's scientific community is eager to push the boundaries of discovery in fields ranging from physics to chemistry.

Collaboration with Fugaku

In a groundbreaking collaboration, 'Reimei' is designed to work alongside RIKEN's renowned supercomputer, Fugaku. This hybrid quantum-high-performance computing (HPC) platform is expected to significantly enhance computational power and speed, promoting scientific methodologies that require extensive computing resources. The integration of these two systems will empower researchers to explore hybrid applications that utilize both quantum and classical computing paradigms.

Dr. Mitsuhisa Sato of RIKEN's Hybrid Quantum HPC Division noted, "The high-fidelity qubits and all-to-all connectivity of 'Reimei' will significantly enhance our research capabilities on the hybrid quantum-HPC platform. We are thrilled to explore new frontiers in scientific research using Quantinuum's system with Fugaku."

A Vision for Future Research

This initiative, supported by Japan's New Energy and Industrial Technology Development Organization (NEDO), demonstrates a strong commitment to advancing quantum technology for research on a global scale. Dr. Rajeeb Hazra, President and CEO of Quantinuum, added, "This deployment marks a crucial step in our global strategy, as it's the first in-situ installation of our technology outside the U.S. We look forward to collaborating with RIKEN's exceptional researchers whose expertise will be pivotal in achieving unprecedented scientific advancements."
