This joint project between the National Institute of Advanced Industrial Science and Technology (AIST), Fujitsu, and the University of Osaka (UOsaka) aims to integrate quantum and classical technologies to realize a practical quantum-HPC hybrid computing infrastructure, named ABCI-Q, for creation of applications and use cases with quantum computers. ABCI-Q consists of a GPU-based supercomputer and three types of quantum computers: a superconducting quantum computer, a neutral atom quantum computer, and an optical quantum computer. As the performance of these quantum computers improves, quantum computations on a scale of 100 logical qubits are expected to become possible around 2030. To prepare for this new stage, it is important to begin small-scale demonstration experiments and accumulate know-how as soon as possible with the currently available quantum and classical technologies. Furthermore, the quantum computers must be matured from laboratory devices to systems that can be operated in data centers to build an open and secure environment in which researchers and developers can freely experiment. As a first step towards achieving them, AIST, Fujitsu, and UOsaka have been integrating the supercomputer and the superconducting quantum computer by introducing OQTOPUS (Open Quantum Toolchain for OPerators and USers) into ABCI-Q for making the most effective use of the quantum and classical technologies. OQTOPUS is practical full-stack open-source operations software suite for cloud-based quantum computing. In addition to providing standard web applications such as job queue and user management, it supports layers close to quantum hardware—including transpilation, hybrid quantum-classical execution, error mitigation, and multi-programming. Our hybrid quantum-classical execution, which occupies a quantum chip and is not interrupted by the other jobs, is an efficient feature that allows the supercomputers to run with minimal idle time and maximizes the potential of quantum and classical technologies. Furthermore, while most conventional cloud quantum computing platforms have been developed in closed and proprietary environments, OQTOPUS has implemented all features openly, making it easier to identify and address issues by leveraging the power of research partners and a quantum computing developer community to maintain an open and secure environment. Current project progress is that initial implementation supporting for basic hybrid job execution where OQTOPUS middleware enables the use of the superconducting quantum computer from the supercomputer has been completed. Based on its evaluation, we will modify our infrastructure, launching a service in 2026. Furthermore, technologies for operating and monitoring the quantum computers will be developed, and the collaboration between the supercomputer and the superconducting quantum computer will be improved. By making this quantum-HPC hybrid computing infrastructure widely available to a diverse range of users, we aim to create market through use cases in various industrial fields and promote industrialization of the quantum technologies.
