France Integrates Lucy Quantum Computer into Supercomputer for Hybrid Computing

• •Lucy is the most powerful photonic quantum computer in Europe, featuring 12 qubits.
• •The system integrates quantum computing with classical supercomputing for enhanced computational tasks.
• •Lucy is expected to be operational soon, supporting applications in various complex fields.

On April 15, 2026, France inaugurated the Lucy photonic quantum computer at the Très Grand Centre de Calcul (TGCC) in Bruyères-le-Châtel. Developed by Quandela, Lucy features 12 physical qubits and is integrated with the Joliot-Curie supercomputer, enhancing hybrid quantum-classical computing capabilities. This integration aims to support complex computational tasks in fields such as energy grid optimization and aerospace design. The project is part of the EuroHPC Joint Undertaking, involving the CEA and GENCI, and reflects Europe's commitment to technological sovereignty. Lucy is expected to become operational in the coming weeks, following its installation in October 2025. The system's photonic technology allows for easier integration into existing infrastructures compared to traditional superconducting quantum computers. This initiative follows the earlier deployment of another Quandela system, Belenos, at the same facility.
