The European High Performance Computing Joint Undertaking (EuroHPC JU) has launched the procurement process for a new EuroHPC quantum computer that will be hosted and operated by LuxProvide in Luxembourg. The system, known as MeluXina-Q, will be integrated with the existing MeluXina supercomputer to support advanced hybrid computing capabilities. The project follows a hosting agreement signed between EuroHPC JU and LuxProvide in December 2024. With a total acquisition budget of up to €11.95m, the initiative will be funded equally by the Digital Europe Programme through EuroHPC JU and the Luxembourg Government. Once operational, the EuroHPC quantum computer will expand Europe’s quantum computing infrastructure, providing researchers, businesses and public sector organisations with access to hybrid classical and quantum computing resources. The system is expected to accelerate scientific research and support innovation across multiple industries. Hybrid quantum and supercomputing capabilities MeluXina-Q will initially feature a quantum processing unit (QPU) equipped with at least 10 semiconductor spin qubits. Planned upgrades over the system’s lifetime will increase this to more than 80 physical qubits, significantly expanding its computational capabilities. By integrating the quantum processor with the MeluXina supercomputer, users will be able to develop hybrid workflows that combine conventional high-performance computing with quantum processing. This approach allows computational tasks to be distributed between classical and quantum systems, improving efficiency for suitable applications. The project forms part of EuroHPC JU’s wider strategy to establish a diverse European quantum computing ecosystem by supporting multiple quantum hardware technologies across member states. Supporting research and industrial innovation When deployed, the system will be accessible through EuroHPC’s infrastructure to a broad community of European users, including academic researchers, industrial organisations and public institutions. It will also join the growing network of EuroHPC quantum systems available through the recently launched EuroHPC quantum access pilot. The new platform is expected to
