RIKEN Scales Quantum-Supercomputing in Japan with ԹϺ System Upgrade

ԹϺ’s H2 quantum computer to expand the scope and accuracy of pharmaceutical and materials science research using the Reimei-Fugaku hybrid compute platform

April 16, 2026

Tokyo, Japan, April 14th, 2026 — ԹϺ, 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 ԹϺ’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, ԹϺ 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 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 ԹϺ, said: “We believe RIKEN’s decision to continue adopting ԹϺ systems to meet its ambitious objectives is a validation of our technology roadmap and a reflection of the success of our valued partnership. With ԹϺ 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 ԹϺ and RIKEN’s collaboration to advance quantum-HPC hybrid infrastructure in Japan. ԹϺ 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.

ԹϺ and bp Collaborate Towards Solving Fundamental Wave Physics Challenges with Quantum Computing

Broomfield, CO, May 20th, 2026 ԹϺ, a leading quantum computing company, today announced the launch of a new quantum project in collaboration with bp, the global integrated energy company, aimed at modernizing how the energy sector maps the Earth’s subsurface to locate oil and gas resources.

Few tasks in today’s oil and gas sector demand as much raw computational power as seismic imaging. Building on a successful pilot that demonstrated feasibility, bp and ԹϺ are now scaling their approach to simulate more complex subsurface properties.

“This has the potential to be a very important industrial use case for quantum computing,” said Dr. Rajeeb Hazra, President and CEO of ԹϺ. “By enabling higher-fidelity data at a lower computational cost than classical computing, we can potentially provide a more efficient path for energy exploration.”

On classical computers, computational requirements, such as memory, scale with spatial resolution, so doubling the resolution of a seismic image can require up to double the computational resources. By contrast, in an ideal scenario, a quantum computer could theoretically achieve the same resolution gains with the addition of a single qubit,1 potentially compressing simulation timelines while also reducing energy consumption.

Hybrid quantum-classical approaches have the potential to further optimize performance, with quantum processors tackling the most demanding calculations while classical systems manage data logic, allowing results to remain grounded in real-world physics.

If successful, this project could demonstrate that quantum computing can help solve real-world bottlenecks in global infrastructure and resource management.

ԹϺ Announces Collaboration with Synopsys Toward Advancing Industrial Design with Quantum Computing

Broomfield, CO, May 19th, 2026 — ԹϺ, a leading quantum computing company, today announced a strategic collaboration with Synopsys, a global leader in electronic design automation and engineering simulation, focused on the integration of quantum computing into the modern engineering toolkit to help overcome the “computational wall” believed to be limiting the pace of industrial innovation.

The Challenge: Designing for Accuracy in the Physical World

Modern industrial design depends on high-fidelity simulation to make better decisions earlier — potentially reducing costly prototypes, shortening development cycles, and improving product performance. Across aerospace and advanced electronics, teams rely on computational fluid dynamics (CFD) and electromagnetic simulation to predict real-world behavior before build and test.

However, as products become more complex, simulation workloads scale dramatically and can require computational resources that exceed the capabilities of even the most advanced classical supercomputers. As a result, engineers must increasingly balance simulation accuracy against runtime, cost and development speed. The collaboration between ԹϺ and Synopsys seeks to overcome these limitations by integrating quantum computing capabilities directly into advanced engineering workflows.

“Our goal is to turn quantum computing into a practical business advantage for the world’s most innovative companies,” said Dr. Rajeeb Hazra, President and CEO of ԹϺ. “By improving how these core design equations are solved, we aim to help innovators explore more accurate models and accelerate breakthroughs in materials and next-generation technologies.”

Transforming Industrial Design with Quantum Computing

The companies aim to build a scalable, end-to-end workflow that integrates quantum algorithms directly into existing industrial software and libraries. By combining the industry-leading accuracy of ԹϺ’s systems with Synopsys’ deep expertise in engineering simulation and design tools, the partnership aims to make quantum computing a functional part of the modern engineering toolkit.

“This partnership is about giving innovators the tools they need to solve the world’s most difficult design challenges,” said Prith Banerjee, Senior Vice President of Innovation at Synopsys. “By integrating quantum computing into today's engineering workflows, we believe we can accelerate innovation while maintaining the standards and reliability that customers trust.”

The collaboration focuses on three key goals aimed at driving value for the engineering sector:

  • Higher Accuracy for the Physical World: Enabling engineers to model critical physical details that were previously too costly for classical supercomputers to capture accurately.
  • Faster and More Cost-Effective Simulations: Accelerating simulation timelines to help companies move from concept to prototype faster while significantly reducing R&D costs
  • Greater Augmentation and Scale for Existing Workflows: Ensuring new quantum-native solvers maintain the rigorous validation standards and modeling intuition that industrial users demand.  

By building on established CFD and electromagnetic capabilities, this effort aims to allow that as quantum computers scale, industrial engineers can explore future computational advantages without having to reinvent their design process. This approach builds on decades of validated engineering expertise while opening a new potential path alongside the new frontier for computing.
