Superconducting Quantum Computing: QSolid Prototype Arrives at JUNIQ

JUNIQ, the Jülich UNified Infrastructure for Quantum Computing, is set to integrate the first operational prototype of a quantum computer developed under the QSolid project. This system, based on superconducting qubit technology, represents a major step toward building a high-performance quantum computer in Germany. With low error rates and a custom-built software stack, the 10-qubit prototype will be connected to JUNIQ via cloud access in the coming weeks, enabling researchers and industry partners to explore quantum computing applications in chemistry, materials science, and medical technology.

QSolid is a collaborative effort involving 25 German institutions and is 90% funded by the Federal Ministry of Education and Research (BMBF) as part of Germany’s strategy for technological sovereignty in quantum computing. The project, coordinated by Forschungszentrum Jülich, aims to scale the system from 10 to 30 qubits while developing new superconducting qubit processors with improved control and energy efficiency. “We have developed a compact but powerful system that is now ready to enter the next phase of development,” said Prof. Frank Wilhelm-Mauch, QSolid project coordinator. “With the funding secured, we can now scale up to a truly remarkable platform.”

A key goal of QSolid is the integration of quantum computing with Jülich’s high-performance computing (HPC) infrastructure, laying the foundation for hybrid quantum-classical computing. “First steps towards a hybrid system that combines quantum and supercomputing have already been taken,” added Prof. Wilhelm-Mauch. As development continues through 2026, the QSolid demonstrator is expected to significantly enhance performance, solidifying Germany’s position as a leader in quantum technology.
