Osaka University, Fujitsu Co., Ltd., Systems Engineering Consultants Corporation (SEC), and TIS Inc. (TIS) announced the release of an open source operating system for quantum computers on GitHub. The system, called the Open Quantum Toolchain for Operators and Users (OQTOPUS), represents one of the world's most comprehensive open source efforts in quantum computing.
OQTOPUS is designed to be flexible and customizable, allowing users to tailor the system to their specific needs. Its release is expected to accelerate the practical deployment of quantum computing by significantly reducing the complexity of setting up and operating quantum systems, especially in cloud environments.
Previously, universities and companies had to develop large amounts of custom software to enable cloud-based quantum computing. With OQTOPUS, the collaborative team simplifies this process by providing a complete, ready-to-use operating system from setup to execution, making quantum computing more accessible than ever.
In addition, the quantum computing cloud service provided by Osaka University has begun integrating OQTOPUS into its operations, and Fujitsu Ltd. will provide the service to research partners using its quantum computers in the second half of 2025.
Looking forward, the research team will advance the development of quantum computing by continuously expanding OQTOPUS's capabilities and developing a thriving global community. Dr. Keisuke Fujii from the Center for Quantum Information and Quantum Biology (QIQB) at Osaka University mentioned: "This will promote the standardization of various quantum software and systems while promoting the creation of innovative quantum applications."
The research was funded by the Japan Science and Technology Agency and Japan's National Institute of Quantum Science and Technology.
