The Jülich Supercomputing Centre (JSC), Quantum Machines, and Arque Systems have announced the first deployment of an NVIDIA DGX Quantum-powered quantum computer at a major supercomputing center. The system is located at JSC in Germany, which operates JUPITER, a supercomputer described as Europe’s fastest. This deployment represents a step in integrating quantum computing capabilities into real-world high-performance computing (HPC) environments.
The NVIDIA DGX Quantum system combines an NVIDIA Grace Hopper Superchip with Quantum Machines’ OPX1000 hybrid quantum-classical controller. The integration enables round-trip data transfer with a latency under 4 microseconds, a reported 1000-fold improvement over previous implementations. The system features Arque Systems’ 5-qubit quantum processor, which uses electron shuttling to couple qubits—an approach intended to enable architectures suitable for quantum error correction (QEC).
The collaboration’s goals include accelerating qubit calibration routines, benchmarking QEC performance, and exploring hybrid quantum-classical algorithm development within an HPC environment. This architecture is designed to run neural networks and machine learning models directly on classical accelerators, such as GPUs, while maintaining low-latency communication with the quantum controller. This capability enables techniques like adaptive calibration and decoder optimization to be executed in real time, which is intended to speed up workflows.
The JUPITER supercomputer, a key component of this initiative, is funded jointly by the European High Performance Computing Joint Undertaking (EuroHPC JU), the German Federal Ministry of Research, Technology and Space (BMFTR), and the Ministry of Culture and Science of the State of North Rhine-Westphalia (MKW NRW) via the Gauss Centre for Supercomputing (GCS). The inauguration ceremony was attended by German Chancellor Friedrich Merz, highlighting the national and European strategic importance of the project. JUPITER is designed to fuse HPC and AI into a single architecture, and the deployment of the NVIDIA DGX Quantum system is positioned as a step toward the future of hybrid supercomputing.
