April 14, 2026 -- Today, the EuroHPC Joint Undertaking (EuroHPC JU) inaugurated Lucy, a new EuroHPC quantum computer, located near Paris, in France, marking a significant step in Europe’s efforts to build world-class, sovereign supercomputing infrastructure.

The inauguration ceremony took place at the Très Grand Centre de Calcul (TGCC) in Bruyères-le-Châtel and was hosted by the CEA, the French Alternative Energies and Atomic Energy Commission, together with GENCI (Grand Équipement National de Calcul Intensif).

The event was attended by Anne Le Hénanff, French Minister for Artificial Intelligence and Digital Affairs, Kilian Gross, Director in the Directorate-General Communication Networks, Content and Technology (DG CNECT) at the European Commission and Anders Jensen, the Executive Director of the EuroHPC Joint Undertaking.

Lucy is Quandela’s state-of-the-art photonic quantum computer ‘MOSAIQ-12’ enabling computations with up to 12 physical qubits. The system will be integrated into the Joliot-Curie supercomputer, and will enable researchers and industry to apply quantum accelerated high-performance computing (HPC-QC) in technological and scientific fields such as material science, meteorology, energy, and advanced engineering.

Anders Jensen, Executive Director of the EuroHPC Joint Undertaking stated:

“Lucy is the fourth EuroHPC quantum computer to be inaugurated. It brings new quantum capabilities to Europe’s supercomputing ecosystem and marks another important milestone for our technological sovereignty. By bringing together quantum and high-performance computing, EuroHPC JU is enabling researchers and industry to tackle complex challenges and unlock new opportunities for innovation across strategic sectors.”

Anne-Isabelle Etienvre, Administrator General of the CEA:

“With Lucy, the CEA is giving new concrete expression to its long-standing commitment to quantum technologies. From the invention of the first qubits by our fundamental research teams—an excellence recently recognised at the highest level—to the operation of breakthrough machines at the TGCC, we are demonstrating the strength of our integrated model. This continuity enables us to transform a technological breakthrough into a sovereign industrial tool. Lucy is now at the service of our researchers, as well as the entire European scientific and industrial ecosystem, to explore new computing horizons.”

Michaël Krajecki, CEO of GENCI:

“With Lucy, the EuroHPC Joint Undertaking, the CEA, and GENCI are providing European and French scientific and industrial communities with a unique, hybrid, and sovereign quantum computing capability. Freely accessible, Lucy is becoming a cutting-edge sovereign asset for research and innovation. Thanks to Quandela’s photonic technology, hosted at the TGCC, the transition to the industrial scale of the quantum era has never seemed so close. This marks a major milestone for France and for Europe.”

Hosted by GENCI, Lucy is installed and operated at the TGCC, a computing centre of CEA and one of France’s three national supercomputing facilities. The system is supplied by a French-German vendor partnership including Quandela and attocube.

The system is now undergoing final calibration and should be available to European end-users in the coming weeks.
