The University of Osaka, Fujitsu Limited, Systems Engineering Consultants Co., LTD. (SEC), and TIS Inc. (TIS) today announced the launch of an open-source operating system (OS) for quantum computers on GitHub, in what is one of the largest open-source initiatives of its kind globally. The Open Quantum Toolchain for Operators and Users (OQTOPUS) OS can be customized to meet individual user needs and is expected to help make practical quantum computing a reality.
Until now, universities and companies seeking to make their quantum computers accessible via the cloud have had to independently develop extensive software to enable cloud-based operation. By offering this open-source OS -covering everything from setup to operation-the research partners have lowered the barrier to deploying quantum computers in the cloud.
Additionally, quantum computing cloud service offered by The University of Osaka has begun integrating OQTOPUS into its operations and Fujitsu Limited will make it available for research partners using its quantum computers in the second half of 2025.
Moving forward, the research team will drive the advancement of quantum computing through the continuous expansion of OQTOPUS's capabilities and the development of a thriving global community. Dr. Keisuke Fujii at the Center for Quantum Information and Quantum Biology (QIQB) of The University of Osaka mentions, "this will facilitate the standardization of various quantum software and systems while driving the creation of innovative quantum applications."
