Germany’s Forschungszentrum Jülich Supercomputing Center has successfully integrated a prototype quantum computer into the center’s JUNIQ (Jülich UNified Infrastructure for Quantum) facility.

The integration was undertaken in collaboration with the QSolid consortium, a group consisting of 26 German institutions working to develop a quantum computer with enhanced error correction.

JUNIQ provides quantum computing access to industry and academia.

The prototype system-integrated quantum computer was made available to external users for an initial two-week test phase, which started on November 17, 2025. The computer currently has a 10-qubit capacity and is accessible via the JuDoor cloud platform, with ParTec, ParityQC, and HQS Quantum Simulations being the first users outside Jülich’s infrastructure to participate in the two-week test run.

Founded in 2022, QSolid has a budget of €76.3 million ($87.8m) and aims to make Germany a world leader in the quantum computing industry by developing both a supply chain and ecosystem for the technology. The Jülich Supercomputing Centre is contributing to two out of the project’s eleven work packages. Other project partners include Eviden, GlobalFoundries, IQM, ParTec, alongside a number of German universities.

“It is an outstanding achievement by our team to have succeeded in building a complete prototype from scratch,” said Frank Wilhelm-Mauch, coordinator of QSolid. “From the chip upwards, it consists of hardware developed at Forschungszentrum Jülich. In addition, another prototype will be launched in January. The feedback from our first users will now be crucial to further optimize the quantum computer.”

He added: “The system integration serves as a blueprint for developing a German quantum computer. From a technical perspective, it represents an ideal starting point for the High-Tech Agenda Germany of the Federal Ministry for Research, Technology, and Space.”
