Orange Quantum Systems reveals OrangeQS Juice today at the APS Global Physics Summit 2025. OrangeQS Juice is a state-of-the-art operating system to operate quantum systems and supports quantum computing research and qubit development.

OrangeQS Juice will be open-sourced and available for the community by the end of 2025. A closed beta starts with the Advanced Quantum Testbed (AQT) at Berkeley Lab, Chalmers Next Labs, the DiCarlo Lab at QuTech and other leading institutes. This closed beta will provide feedback and shape final features.

OrangeQS Juice will enable quantum R&D labs to operate their full-stack R&D lab with one framework. This solves major hurdles in working with these complex systems, like pinpointing issues, correlating the state of all components to qubit behavior and collaborating between colleagues.

• Open – Conceived as an open platform to build on, with an open-sourced hardware abstraction layer and open APIs to integrate custom or third-party software tools.
• Quantum – Dedicated to quantum R&D, with pre-installed packages, fast system-wide debugging and the ability to handle large datasets.
• Together – Designed for multi-user and remote operation, with database management for reliable workflows and streamlined experiment scheduling and monitoring.

Labs need a dedicated operating system optimized for quantum hardware and software integration. They require control and monitoring of the full stack, including all instruments and the cryostat.

OrangeQS Juice was initially developed to operate a utility-scale quantum chip test system. The first 150+ qubit test system using this framework was the OrangeQS MAX. After its deployment at IQM in Helsinki, OrangeQS generalized the operating system to support more flexible and experimental quantum systems, typical for quantum R&D labs.

The framework will be tested in a closed beta at the Advanced Quantum Testbed at Berkeley Lab, Chalmers Next Labs and the DiCarlo Lab at QuTech, with several other leading institutes expressing interest. Testing begins in the summer of 2025, with a focus on improving usability, stability and scalability.
