The J\u00fclich Supercomputing Centre (JSC)<\/a>, Quantum Machines<\/a>, and Arque Systems<\/a> have announced the first deployment of an NVIDIA DGX Quantum<\/a>-powered quantum computer at a major supercomputing center. The system is located at JSC in Germany, which operates JUPITER<\/a>, a supercomputer described as Europe\u2019s fastest. This deployment represents a step in integrating quantum computing capabilities into real-world high-performance computing (HPC) environments.<\/p>\n The NVIDIA DGX Quantum system combines an NVIDIA Grace Hopper Superchip<\/a> with Quantum Machines\u2019 OPX1000<\/a> 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\u2019 5-qubit quantum processor, which uses electron shuttling to couple qubits\u2014an approach intended to enable architectures suitable for quantum error correction (QEC).<\/p>\n The collaboration\u2019s 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.<\/p>\n The JUPITER supercomputer, a key component of this initiative, is funded jointly by the European High Performance Computing Joint Undertaking (EuroHPC JU)<\/a>, the German Federal Ministry of Research, Technology and Space (BMFTR)<\/a>, and the Ministry of Culture and Science of the State of North Rhine-Westphalia (MKW NRW)<\/a> via the\u00a0Gauss Centre for Supercomputing<\/a>\u00a0(GCS). The inauguration ceremony was attended by German Chancellor Friedrich Merz<\/a>, 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.<\/p>\n Read the full announcement from the J\u00fclich Supercomputing Centre on the JUPITER inauguration here<\/a>, and the news of the NVIDIA DGX Quantum deployment in the Quantum Machines press release here<\/a> and the PR Newswire press release here<\/a>.<\/p>\n September 18, 2025<\/p>\n
