EuroHPC JU Launches Procurement for MeluXina-Q Quantum Computer in Luxembourg

The European High Performance Computing Joint Undertaking (EuroHPC JU) has launched the procurement process for a EuroHPC quantum computer, designated MeluXina-Q, to be hosted and operated by LuxProvide in Luxembourg and integrated into the EuroHPC supercomputer MeluXina. The total acquisition budget reaches up to €11.95 million ($13.6 million USD), co-financed equally by the EuroHPC JU through the Digital Europe Programme and the Luxembourg Government. The system will initially feature a quantum processing unit with at least 10 semiconductor spin qubits, with upgrades foreseen over its lifetime to reach a total of over 80 physical qubits.

Spin Qubit Architecture and Scaling

MeluXina-Q employs semiconductor spin qubits realized in silicon, a modality selected to complement the existing portfolio of EuroHPC quantum systems and to leverage Europe’s semiconductor manufacturing capabilities. The initial quantum processing unit must deliver at least 10 physical qubits, with the procurement covering acquisition, delivery, installation, and ongoing hardware and software maintenance.

Over the system lifetime, upgrades are specified to expand capacity beyond 80 physical qubits. Integration with MeluXina will support hybrid classical-quantum workflows, allowing users to combine high-performance computing resources with quantum processing for optimization, simulation, and machine-learning tasks.

The tender closes on 1 September 2026. Technical requirements emphasize European supply-chain considerations and compatibility with the host infrastructure operated by LuxProvide. This procurement continues the EuroHPC strategy of deploying diverse quantum modalities, including trapped-ion, superconducting, photonic, and now additional semiconductor spin-qubit platforms, across multiple Member States.

European Access and Application Scope

Once operational, MeluXina-Q will join the suite of EuroHPC quantum computers already accessible through the EuroHPC quantum access pilot call. Current systems include PIAST-Q in Poland, VLQ in Czechia, Euro-Q-Exa in Germany, Lucy in France, EuroQCS-Spain in Spain, and SOL in Italy. Access will be available to the scientific community, industry, and the public sector across Europe.

Target application domains span automotive (quantum-enabled machine learning for routing), energy (adaptive optimization), finance (risk assessment), and healthcare (quantum chemistry and molecular dynamics simulations). The hosting agreement between EuroHPC JU and LuxProvide was signed in December 2024. By adding a silicon spin-qubit platform integrated with an established EuroHPC supercomputer, the initiative expands the range of hybrid architectures available to European researchers and industrial users.

Bottom Line

EuroHPC JU procurement advances Luxembourg’s contribution to Europe’s diversified hybrid quantum computing infrastructure via MeluXina-Q.
