HSBC uses our Quantum Origin QRNG to pilot quantum-safe technology for tokenized gold

TOKYO — April 14, 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.

The R&D Centre, together with the planned deployment of a Quantinuum Helios system in Singapore, aims to accelerate industrial collaboration across pharma, materials and finance, while bolstering the local quantum ecosystem and workforce 

March 11, 2026 – Singapore – Quantinuum, a leading quantum computing company, today announced the establishment of a new R&D and Operations Centre (the “Centre”) in Singapore, marking its formal expansion into Singapore. This important development will enable Quantinuum to deepen collaboration with the nation’s research and industrial ecosystem, together with the company’s plan to deploy its Helios quantum computer in Singapore later this year. 

Singapore’s early investment in quantum has positioned the nation to capture value as quantum systems move toward real-world use. In his national budget speech last month, Prime Minister Mr. Lawrence Wong highlighted Quantinuum as an industry leader, emphasizing that Helios will enable Singaporean researchers and companies to work on meaningful projects. 

The new Centre will bring together Quantinuum staff with local researchers and industry partners to co-develop commercially relevant solutions across pharma, materials science, finance, and other sectors. It will also serve to help advance Singapore’s national priorities under its National Quantum Strategy by strengthening long-term R&D capabilities and workforce development, helping position Singapore as a global hub for quantum technology.

The Centre’s establishment is supported by the Singapore Economic Development Board (EDB) and builds on Quantinuum’s close partnership with Singapore’s National Quantum Office (NQO) through the National Quantum Computing Hub. The National Quantum Strategy is developed and implemented by NQO, which is hosted in the Agency for Science, Technology and Research (A*STAR), and funded by the National Research Foundation (NRF).

As part of its commitment to developing a robust local ecosystem and support for innovation across the full quantum value chain, Quantinuum is collaborating with pioneering startups in Singapore, including Entropica, which accesses Quantinuum systems through its Startup Partner Program, and Squareroot8, with whom Quantinuum signed a Memorandum of Understanding today to co-develop quantum communications applications. 

Official Statements

• Dr. Rajeeb Hazra, President and CEO of Quantinuum, said: “We believe there are three pillars to a holistic strategy for building a sustainable quantum frontier: use cases, infrastructure, and workforce. Singapore provides an exceptional foundation for this approach, and we are proud to contribute our experience in ecosystem development as we build a leading quantum ecosystem together."
• Dr. Marvin Lee, Country Leader for Quantinuum Singapore, who recently joined the company following senior appointments at A*STAR, EDB, and NRF, where he played a key role in shaping the National Quantum Strategy, said: “The new Centre will enable local talent and industry to work hands-on with quantum technologies, co-develop solutions aligned with national priorities, and support high-value jobs. We are committed to building long-term capability and resilience in Singapore’s digital economy."
• Mrs. Josephine Teo, Minister for Digital Development and Information, a key advocate of the National Quantum Strategy, joined Quantinuum today as the Guest of Honour at the official opening of its new Centre, commemorated by a formal ribbon-cutting ceremony. She said: “Singapore aims to be a global hub for the development of algorithms and applications for quantum computers. We will tap on our strengths in sectors of potential application, such as finance, logistics, and pharmaceuticals. Doing so will not only benefit these industries in Singapore, but elsewhere in the world.” 
• Mr. Pee Beng Kong, Executive Vice President, Singapore Economic Development Board, said: “Quantinuum’s expansion into Singapore marks an important step in translating quantum research into real-world industry applications. The Helios system and new R&D Centre will enable local companies and researchers to collaborate on next-generation solutions in areas such as drug discovery, materials innovation, and financial optimisation. This investment will deepen partnerships across our industry and research ecosystem and build high-value quantum capabilities from Singapore.”
• Mr. Ling Keok Tong, Executive Director of the National Quantum Office, said: “Quantinuum's R&D Centre and the Helios deployment create opportunities for Singapore, giving our researchers hands-on access to advanced quantum hardware, and moves us closer to demonstrating real quantum advantage in drug discovery, portfolio optimisation, amongst others. This is a boost to our quantum research and talent development, as well as our efforts in building a robust quantum ecosystem.”

The new Centre represents an important step in Quantinuum’s international expansion and its commitment to collaborating with partners in key innovation hubs. Quantinuum looks forward to continued collaboration with Singapore’s research and industry ecosystem to advance the development and application of quantum technologies.
