The roadmap is built on the foundations of Quantinuum’s fully scalable quantum charge-coupled device (QCCD) architecture, including a universal gate set and high-fidelity physical qubits uniquely capable of supporting reliable logical qubits. For four years now, Quantinuum has remained steadfast in providing data along with peer-reviewed papers to show the science and engineering work behind these methodical advances.

“Our next system, Quantinuum Helios, will support enough logical qubits to unlock scientific and mathematics advances that will clearly surpass classical computing,” Hazra said. “Our roadmap then draws a direct line to hundreds of logical qubits, at which point quantum computing will outperform classical computing to address a broad range of scientific problems in areas like finance, chemistry, and computational biology. We also know, from experience, that utility in the form of applications that are suitable for global enterprises and governments will likely bubble to the surface and increase rapidly over the next 18 months. Our quantum computers are already impossible to simulate classically.”

Quantinuum also announced another milestone today in collaboration with Microsoft: achieving 12 logical qubits on the newly updated 56-qubit System Model H2 quantum computer, a 3x advance over the four logical qubits the companies announced in April. Microsoft also used the System Model H1 quantum computer to run the first ever chemistry simulation using reliable logical qubits combined with AI and HPC to produce results within chemical accuracy. Finally, Quantinuum and Microsoft have completed the integration of Quantinuum’s InQuanto™ computational quantum chemistry software package with Azure Quantum Elements, making it available to customers through private preview.

“The collaboration between Quantinuum and Microsoft has established a crucial step forward for the industry and demonstrated a critical milestone on the path to hybrid classical-quantum supercomputing capable of transforming scientific discovery,” said Dr. Krysta Svore – Technical Fellow and VP of Advanced Quantum Development for Microsoft Azure Quantum.

RIKEN Scales Quantum-Supercomputing in Japan with Quantinuum System Upgrade

Tokyo, Japan, April 14th, 2026 — Quantinuum, a leading quantum computing company, today announced that RIKEN, Japan’s premier national research institute, has procured its System Model H2 quantum computer to scale the capability of “Reimei-Fugaku,” a hybrid quantum-supercomputer platform in Japan.

The Reimei-Fugaku platform represents the frontier of computing technology. Launched in the spring of 2025, it combines Quantinuum’s "Reimei" quantum system with RIKEN’s "Fugaku," one of the world’s fastest supercomputers—more formally known as a high-performance computing (HPC) system.

Now, the hybrid compute platform is getting a substantial upgrade. Earlier this month, Quantinuum delivered its H2 system to RIKEN’s research facility near Tokyo, where assembly is already underway to replace its predecessor, System Model H1, which Reimei has been based on to date. The newer-generation, 56-qubit system is engineered for high-fidelity operations that can reduce time-to-solution, enable larger workloads, and support higher-value applications.

Technology leaders see hybrid compute systems as a practical way to overcome the limits of classical HPC. By combining the significant data-processing power of HPC with a quantum computer’s ability to model complex molecules and materials, researchers could be enabled to solve specialized mathematical problems that are impractical for classical systems to handle alone.  

Researchers have already demonstrated this potential using the current Reimei-Fugaku platform. In a workflow with relevance potentially extending to future pharmaceutical applications, they successfully simulated biomolecular reactions at an accuracy that would be infeasible for HPC to achieve in isolation.

With multiple studies in chemistry and materials science already underway on the platform, this H2 upgrade is expected to accelerate research and unlock even more complex scientific discoveries across disciplines.

Dr. Mitsuhisa Sato, Division Director of the Quantum-HPC Hybrid Platform Division, RIKEN Center for Computational Science, said: “Since its installation in February 2025, Reimei H1 has been widely used by JHPC-quantum users and has delivered significant results, thanks to its high fidelity and flexible qubit connectivity. The upgrade to H2 is exactly what we have been eagerly anticipating, and with its 56 qubits, we expect it to play a key role in demonstrating quantum advantage through quantum–HPC hybrid computing.”

Dr. Rajeeb Hazra, President and CEO of Quantinuum, said: “We believe RIKEN’s decision to continue adopting Quantinuum systems to meet its ambitious objectives is a validation of our technology roadmap and a reflection of the success of our valued partnership. With Quantinuum and RIKEN’s combined leadership in quantum and HPC, respectively, we expect to continue pushing the boundaries of computing to address some of the most critical and complex challenges facing science and industry today.”

This development reflects the continued progress of Quantinuum and RIKEN’s collaboration to advance quantum-HPC hybrid infrastructure in Japan. Quantinuum intends to continue working with the country’s research community to accelerate real-world use cases and contribute to the growth of its quantum ecosystem.
