On March 24, Fujitsu, Osaka University, SEC, and TIS announced the open-source release and operational launch of “Open Quantum Toolchain for Operators and Users,” a fundamental software suite for quantum computing. This software provides a comprehensive foundation for quantum computer cloud services, integrating multiple key components.
The toolchain consists of several layers: a front-end layer enabling users to create and input quantum programs, a cloud layer managing user and job data, a back-end layer comprising quantum computers and control servers, and an operational layer ensuring stable cloud service performance. Currently, this software is implemented in the cloud service of Osaka University’s third domestically released quantum computer, allowing users to develop and execute quantum programs in Python via the cloud.
Fujitsu has also announced plans to introduce this software into quantum computers deployed in its joint research projects with companies, starting in the latter half of 2025. Developing quantum computing systems requires a broad spectrum of software functionalities, including job management, scheduling, quantum program conversion and optimization, and calibration. This initiative offers these components as one open-source package. This aims to lower entry barriers for new developers. It will also expand quantum software development and speed up innovation in the field.

Fujitsu expects the open-source release to build a global community for quantum computing software. This will boost progress and reinvigorate the industry. The company also hopes this initiative will help create real quantum computing solutions. These solutions aim to tackle important societal challenges.
