Germany Secures Quantum Future: QSolid Integrates Landmark 10-Qubit Prototype into Europe’s Premier Supercomputing Hub
The German-led QSolid group incorporated a 10-qubit quantum computer into JSC JUNIQ, advancing European quantum technology. This strengthens Germany’s standing in the global quantum computing race and promotes its autonomous, industrially relevant ecosystem goal.
The freshly developed 10-qubit system facilitates cloud-based quantum hardware access for researchers and industry partners. The system was created solely with hardware constructed by researchers at Forschungszentrum Jülich and will be made available via the JuDoor cloud platform for a rigorous two-week initial test phase starting on November 17, 2025. For theoretical quantum research to be translated into real-world, useful applications, accessibility is essential.

The Quantum-HPC Nexus: Pioneering Hybrid Computing
With a particular emphasis on the development of a vital hybrid quantum-classical computing model, the strategic significance of this integration cannot be emphasized. QSolid is promoting an architectural strategy that is generally accepted as the best practical means of attaining Quantum Advantage by putting the quantum system right next to one of Europe’s top high-performance computing (HPC) centers. When a quantum machine can solve a problem more quickly or effectively than a classical one, this is known as quantum advantage.
Being both physically and virtually close to enormous classical supercomputers, such those at Jülich, makes it possible to coordinate extremely complicated computations with ease. Particular computing tasks are best performed by quantum computers, but data handling, control, error correction, and the pre- and post-processing of quantum algorithms require classical supercomputers.
As stressed by QSolid project coordinator Prof. Dr. Frank Wilhelm-Mauch, a good system integration “is critical for the compatibility and interplay of quantum and classical components.” The JUNIQ infrastructure is expressly built to serve as a hub, and it is built on this defining interaction. For full-stack hybrid applications, this hub enables users to directly combine a variety of quantum technologies, including the QSolid prototype, with classical computer resources. This action successfully turns quantum computing from a standalone experimental project into a comprehensive, industrial-grade computational tool.
Germany’s Ambitious National Quantum Strategy
As one of Germany’s biggest and most ambitious collaborative efforts devoted to quantum computing, the QSolid project is much more than merely an academic endeavor. This enormous project, which has a total expenditure of €76.3 million (about $88.4 million USD), is supported by a significant financial commitment. The German Federal Ministry of Education and Research is firmly committed to achieving the objectives set forth in the “High-Tech Agenda Germany,” as evidenced by its substantial financial support.
Developing a comprehensive quantum computer system that is truly competitive on the global stage is QSolid‘s main long-term goal. Low error rates, high fidelity, and industrial robustness are required for this future technology. Despite requiring extremely intricate cryogenic cooling systems, the current 10-qubit prototype uses superconducting circuits, a technology known for its relative maturity and scalability potential. Forschungszentrum Jülich’s successful in-house creation of this hardware is a significant step in reducing Germany’s dependency on foreign proprietary technologies and creating technological sovereignty in this vital area.
In a nationwide research and computing network, this current accomplishment serves as a vital template for the development, integration, and operation of bigger quantum systems that are expected to significantly rise in qubit count. From an experimental prototype to a stable, fully functional quantum computer, a seamless transition depends on the scalable and modular architecture that is now being pioneered.

Deep Collaboration Forges the Software Stack
The gear deployed successfully is just half the battle. In order for the system to be genuinely useful, it needs an advanced, industrial-grade software stack that can handle intricate error mitigation, manage quantum firmware, and interface with the extensive resources of the traditional HPC infrastructure.
This crucial software layer was created through close cooperation with a number of important industry partners, demonstrating the project’s commitment to building a profitable ecosystem. The components required for the quantum firmware were supplied by Qruise and Eviden, a significant European player in digital transformation and IT, which also made sure the essential high-performance computing (HPC) capabilities were available. As the quantum computer’s operating system, quantum firmware controls the intricate control patterns and pulses required to work with the sensitive qubits.
In order to guarantee that all of the hardware, software stack, control electronics, and cryogenics components operate in perfect harmony, Forschungszentrum Jülich took on the crucial task of overall system integration.
The involvement of the initial group of external users in the test run further solidifies the project’s industrial usefulness. Among the principal businesses participating are:
- ParTec is a company that focusses on system management and supercomputing software.
- ParityQC, whose goal is to create new quantum algorithms and architecture.
- Experts in using quantum computation in disciplines like materials science and chemistry are HQS Quantum Simulations.
Their input throughout the stress-test stage will be crucial for improving the prototype and determining how the larger scientific and industrial community will interact with it.
Paving the Way for National Quantum Access
Access to this new national quantum resource through the JuDoor cloud platform democratizes access to state-of-the-art quantum hardware. To work with such machines in the past, researchers need physical access to a specialized laboratory setting. Researchers in Germany and Europe can now submit quantum jobs remotely from universities, startups, and huge industrial research departments, greatly speeding up the creation of algorithms and the investigation of real-world applications.
The completeness and industrial integration of the existing 10-qubit count make it significant even though it is little in comparison to the greatest global systems. As a full-stack, locally produced system, it was constructed in accordance with strict industry standards and seamlessly integrated into an HPC environment at production level. The next generation of QSolid devices, which are expressly anticipated to scale quickly, are made possible by this accomplishment.
In summary
The QSolid project’s successful integration of its prototype into the JUNIQ infrastructure is a threefold accomplishment: a domestic quantum hardware technological breakthrough; a strategic success in establishing the hybrid quantum-classical computing model; and a political success in providing a concrete milestone for the country’s High-Tech Agenda. It is a crucial step that will position Germany to go from being a consumer of quantum technology to a major producer on a worldwide scale, prepared to provide actual computing power to meet the challenges of the twenty-first century.
