Quantinuum together with Mitsui advance unforgeable quantum tokens over fibre network in first ever trial
- First successful delivery of quantum tokens using commercial QKD hardware, demonstrating fast transaction verification at the point of exchange - a crucial step toward quantum-enhanced financial security and a major advance for QKD.
- Quantum tokens are designed to provide unforgeability, privacy, and fast settlement, in a single financial instrument. No previous technology can deliver these three combined benefits.
- In the world’s first implementation using off-the-shelf hardware, quantum tokens were transmitted across 10km of fibre in Tokyo, using commercial quantum key distribution (QKD) devices provided by NEC*.
- This is a pivotal step towards the deployment of ultra-high-security quantum tokens in use cases such as tokenized asset security and high-speed trading.
Tokyo, Japan and Broomfield, Colorado - November 18th, 2024 — In a long anticipated trial, Quantinuum ("Quantinuum", Head Office: Broomfield, Colorado, U.S.A., CEO: Rajeeb Hazra), together with Mitsui & Co., Ltd. ("Mitsui", Head Office: Tokyo, President and CEO: Kenichi Hori) and NEC ("NEC", Head Office: Tokyo, President and CEO: Takayuki Morita) today announced the successful delivery of quantum tokens across a 10km fibre-optic network in Japan. This is the first time such a delivery has been accomplished.
Quantum tokens are a new financial instrument that take advantage of the properties of quantum physics to meet the robust demands of asset trading without the communication overheads required by traditional financial systems. Quantum tokens are transmitted across fibre-optic quantum key distribution (QKD) networks, which are rapidly expanding around the globe. Today's announcement with Mitsui demonstrates growing industry recognition of quantum tokens' potential in financial services.
Ilyas Khan, Founder and Chief Product Officer at Quantinuum, said: “The original motivation for quantum communications was the exchange of money, as envisaged by Stephen Wiesner. Today, we have demonstrated real-world security enhancements for financial systems using off-the-shelf quantum communications hardware. This opens the door to a new era in quantum-enhanced security with wide applicability, providing commercial organisations with something concrete to utilise.”
Koji Naniwada, Deputy General Manager, Quantum Innovation Dept. at Mitsui, said: “Quantum tokens will increase the security of digital assets, while improving transaction performance and maintaining privacy. These topics are critical for our customers and partners in the financial sector and this demonstration is a valuable outcome of our partnership with Quantinuum.”
Naoki Ishida, Director with the Trading and Service Solution Department at NEC, said: “We are the first to provide a platform for realizing a quantum token system using NEC’s quantum key distribution (QKD) devices. Based on the results of this trial between Mitsui & Co. and Quantinuum, we will continue to work towards the social implementation of quantum cryptography technology.”
Quantum tokens are designed to use quantum physics to prevent forgery, while ensuring transactions can be settled near-instantly, whereas traditional payments systems rely on double-entry bookkeeping to prevent double-spending of funds. This adds time, overhead and risk to every transaction, as digital systems are consulted to confirm funds are available and to settle transactions.
Quantum tokens instead rely on the no-cloning theorem of quantum physics to prevent forgeries and double-spending. Only the intended recipient will receive the correct token data, which can only be spent at one location in the future. This enables near-instant transaction settlement by removing the need to check multiple systems or wait for network confirmations.
As demonstrated in Quantinuum’s recent work with HSBC, securing digital assets in the quantum-age is growing in urgency. The financial sector is increasingly looking to quantum technology to solve these complex problems with the power of nature.

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.
