Quantinuum Enhances Quantum Supercomputing Capabilities at RIKEN in Japan

Quantinuum Upgrades Quantum Computing at RIKEN

In a significant move for the field of quantum computing, Quantinuum has announced that RIKEN, Japan's leading national research institute, has acquired their latest quantum computer, the System Model H2. This acquisition will enhance the capabilities of RIKEN's existing hybrid supercomputing platform known as Reimei-Fugaku, which integrates the quantum computing power of Quantinuum with one of the fastest supercomputers in the world, Fugaku.

Launched in Spring 2025, the Reimei-Fugaku platform represents a fusion of cutting-edge technology that combines high-performance computing (HPC) with quantum processing capabilities. The recent deployment of the H2 system is expected to serve as a robust upgrade over its predecessor, the H1 system, which has been operational since February 2025. The H2 features an impressive 56 qubits and is designed to operate with high fidelity, allowing researchers to tackle larger computational workloads while significantly reducing resolution times.

The collaboration between RIKEN and Quantinuum aims to address the limitations of traditional HPC systems by utilizing the unique advantages of quantum computing. By merging the extensive data processing capabilities of HPC with the quantum computer’s ability to model complex molecules and materials, researchers can approach specialized mathematical problems that were previously deemed impractical for classical systems alone.

Previously, researchers employed the Reimei-Fugaku platform to simulate biochemical reactions with a level of precision unachievable by high-performance computing alone. This capability is particularly relevant to the pharmaceutical industry, where understanding molecular interactions can lead to groundbreaking advancements in drug development.

As various studies focusing on chemistry and materials science are currently underway, the H2 upgrade is expected to expedite research efforts and pave the way for more intricate scientific discoveries across multiple disciplines. Dr. Mitsuhisa Sato, head of the Quantum Hybrid-HPC Platform Division at RIKEN, emphasized the importance of this upgrade, stating, "The H1 system has already driven significant results thanks to its high fidelity and flexible qubit connectivity. The anticipation for H2 signifies its role in demonstrating quantum advantage through hybrid computing applications."

Dr. Rajeeb Hazra, CEO of Quantinuum, noted that RIKEN's decision to adopt their quantum systems validates their technological roadmap and reinforces the fruitful collaboration between the two entities. He expressed optimism about continuing to push the boundaries of computing to tackle some of the most pressing scientific and industrial challenges.

This advancement is not just a step forward for RIKEN but also reflects the ongoing partnership between RIKEN and Quantinuum in enhancing Japan's quantum-HPC infrastructure. With intentions to further engage with the research community in Japan, Quantinuum aims to accelerate practical applications and contribute to the growth of Japan's quantum ecosystem.
