MeluXina-Q will initially be equipped with a quantum processing unit (QPU) with at least 10 semiconductor spin qubits. Over the lifetime of the system, upgrades are foreseen to reach a total of over 80 physical qubits. This quantum computer will be part of the EuroHPC supercomputing infrastructure and enable hybrid classical‑quantum workflows. The procurement is the continuation of EuroHPC's commitment to diversifying quantum computing modalities across Europe. Once deployed, the system will be available to a broad range of European users, including the scientific community, industry and the public sector, joining the other EuroHPC quantum computers that are now accessible through the newly launched EuroHPC quantum access pilot call. Meluxina-Q will enable groundbreaking research and industrial innovation across a wide range of application domains spanning from automotive (quantum-enabled machine learning for expedited routing), energy (adaptive optimisation), finance (risk assessment) to healthcare (quantum computing-enabled quantum chemistry and molecular dynamics simulations). More details The closing date for submission of an application to tender is 1st September 2026. More details on the call are available on this dedicated webpage. The total acquisition budget of the system is up to EUR 11,95 million, which will be co-financed equally by the EuroHPC JU with budget coming from the Digital Europe Programme (DEP) and by the Luxembourg Government (50%). Background The hosting agreement between EuroHPC JU and LuxProvide was signed in December 2024. To date, the EuroHPC JU has procured and inaugurated six quantum computers, located across Europe: - PIAST-Q in Poznań, Poland, - VLQ in Ostrava, Czechia, - Euro-Q-Exa in Munich, Germany, - Lucy near Paris, France - EuroQCS-Spain in Barcelona, Spain - SOL, in Bologna, Italy. Researchers, public institutions, and industry across Europe can now request free access to some of these quantum computers through the EuroHPC Quantum Access Pilot call . This unprecedented
