PRESS RELEASE — QunaSys Inc. (headquartered in Bunkyo-ku, Tokyo; Representative Director and CEO: Tennin Yan; hereinafter “QunaSys”), a company specializing in the development of quantum computing algorithms and software, announced that its quantum software development kit “QURI SDK Enterprise” has been officially adopted for RIKEN’s Quantum-HPC Hybrid Platform as part of the “JHPC-quantum” project.
JHPC-quantum is a project commissioned by NEDO (New Energy and Industrial Technology Development Organization) under the jurisdiction of the Ministry of Economy, Trade and Industry (METI). The project has developed JHPC-quantum platform for quantum-HPC hybrid applications by linking the supercomputer Fugaku and the IBM Quantum System Two “ibm_kobe” at the RIKEN Center for Computational Science (R-CCS) in Kobe with the trapped-ion quantum computer “Reimei” (Quantinuum System Model H2) at RIKEN’s Wako campus in Saitama.
With this adoption, JHPC-quantum users will be able to access quantum devices from Fugaku’s compute and pre/post nodes through QURI SDK Enterprise. The SDK incorporates state-of-the-art quantum-HPC hybrid algorithm libraries, including QSCI (Quantum Selected Configuration Interaction) and ADAPT-QSCI, supporting computation in fields such as quantum chemistry, materials science, and CAE (Computer-Aided Engineering), with a view to future practical applications. Comprehensive documentation, sample code, and toolchains allow researchers to begin development quickly.
QURI SDK Enterprise supports both the IBM Quantum System Two and the Quantinuum System Model H2, helping researchers build computational workflows that leverage the characteristics of each quantum device. On the HPC side, it supports Fugaku (compute and pre/post nodes) and JHPC-quantum GPU supercomputer “ROQUO”, the NVIDIA GB200 NVL4-based cluster. In both environments, quantum circuit simulation can be run with MPIbased distributed parallelism, using mpiQulacs as the simulator on Fugaku’s compute nodes and a cuQuantum-based backend on ROQUO. Parallel computation spanning multiple nodes and processors makes it possible to simulate quantum circuits at scales beyond the reach of a single node. QunaSys will continue to expand this environment step by step toward utilityscale quantum-HPC hybrid computing.
Outlook
Building on this milestone, QunaSys will continue to deepen its collaboration with RIKEN. By expanding the functionality of QURI SDK Enterprise and its support for additional devices and HPC environments, and through collaboration with RIKEN and other research institutions and industry both in Japan and abroad, QunaSys will drive the real-world deployment of quantum-HPC hybrid technology and contribute to the development of Japan’s quantum industry.
Comments on the Adoption
Mitsuhisa Sato, Division Director of Quantum-HPC Hybrid Platform Division, RIKEN Center for Computational Science (R-CCS)
The Test User Program, which JHPC-quantum Project is also running, has likewise shown strong demand for QURI SDK Enterprise, which is why we decided to adopt it this time. We hope this will be an opportunity to deepen our collaboration with QunaSys within the project and to make the project’s achievements even greater.
Tennin Yan, CEO, QunaSys Inc.
QSCI is a quantum-HPC hybrid algorithm developed by QunaSys. It is now one of the most widely used approaches to quantum-HPC hybrid computing worldwide, and has led to a wide range of research advances, including work to optimize the algorithm for Fugaku and other supercomputers. For quantum computing to deliver practical value, it is essential that these advances be readily accessible to all users, including those in industry. QURI SDK Enterprise brings together algorithms such as QSCI with an easy-to-use environment that lets anyone work across Fugaku, “ROQUO,” and quantum computers. We see this deployment as an opportunity to deepen our collaboration with RIKEN and further accelerate the research and development of quantum-HPC hybrid applications.
