Lucy
Digital Quantum Computer
The most powerful universal photonic quantum computer available in Europe.
Deployed in October 2025
EuroQCS-France “Lucy”
Quandela in consortium with attocube systems AG have been selected by EuroHPC Joint Undertaking and EuroQCS-France to deliver a universal photonic quantum computer, with at least 12 qubits, the most powerful in Europe.
The system, called Lucy, owned by EuroHPC and co-acquired by GENCI, will be hosted and operated by CEA at TGCC.
It will be coupled to the Joliot-Curie supercomputer, and will be made available to scientific communities in 2025 as part of open research.
