The QSolid team has reached a major milestone: for the first time, external users have been granted access to a QSolid quantum computer prototype. Developed at Forschungszentrum Jülich and integrated into the Jülich Supercomputing Centre’s infrastructure (JUNIQ), the system is being tested in a dedicated two-week pilot phase starting in November 2025.
This achievement comes just three and a half years after the project’s launch and represents a key step toward making quantum computing accessible beyond controlled laboratory environments. The prototype, currently operating with 10 qubits, can be accessed via the JuDoor cloud platform, allowing selected external partners to test its capabilities in practice.
From prototype to integrated quantum ecosystem
A central aspect of this milestone is the successful system integration of the quantum computer into an HPC environment. This integration enables hybrid workflows that combine classical supercomputing with quantum processing, an essential requirement for real-world applications. The achievement was made possible through close collaboration between research institutions and industrial partners, who jointly developed the necessary software stack and system components.
The initial group of external users includes industrial and research partners, whose feedback will play a crucial role in refining both hardware and software. Further improvements are already planned, including upgraded quantum chips and additional testing phases with enhanced system performance.
A step toward scalable quantum applications
Providing early access to external users marks an important transition from experimental setups to application-oriented quantum computing. It allows researchers and industry partners to explore practical use cases, test hybrid computing approaches, and contribute to the development of future quantum systems.
More broadly, this milestone highlights the rapid progress of the QSolid project and its role in strengthening Germany’s position within the global quantum landscape. By combining quantum technologies with established HPC infrastructures, the project is laying the groundwork for scalable and usable quantum computing solutions.
