Paris, France – 23 octobre – Quandela, GENCI et le CEA annoncent la livraison de Lucy, un ordinateur quantique photonique universel de 12 qubits, au Très Grand Centre de calcul (TGCC) du CEA. Le système, livré par le consortium franco-allemand Quandela – attocube systems AG, a été acquis par l’entreprise commune EuroHPC dans le cadre du consortium EuroQCS-France.

Une nouvelle capacité quantique européenne

Lucy, l’ordinateur quantique photonique le plus puissant jamais déployé dans un centre de calcul européen, vient d’être installé au TGCC. Doté de 12 qubits photoniques, il offre aux chercheurs et aux industriels une plateforme inédite pour tester des algorithmes quantiques, explorer des workflows hybrides HPC–quantique et développer des applications de première phase en optimisation, chimie et machine learning.

Lucy est fortement orienté vers les usages. Hébergé et opéré au TGCC du CEA, où il est couplé au supercalculateur Joliot-Curie, il sera accessible à une large communauté d’utilisateurs européens. Les premiers cas d’usage couvrent notamment l’optimisation des réseaux énergétiques et l’intégration des énergies renouvelables, l’optimisation de portefeuilles financiers et la modélisation des risques, la logistique et les chaînes d’approvisionnement, ainsi que la conception aéronautique, les matériaux et l’optimisation de trajectoires.

Ces cas d’usage renforcent la position de l’Europe à la pointe de la recherche quantique, tout en préparant les acteurs industriels aux futures applications.

Un ordinateur quantique fabriqué dans l’Union européenne

Lucy a été acquis par EuroHPC dans le cadre du consortium EuroQCS-France.[1] S’appuyant sur les déploiements réalisés chez OVHcloud en 2023 et dans les datacenters d’Exaion au Canada en 2024, il marque une nouvelle étape du développement du quantique en Europe.

Assemblé en douze mois dans les installations de Quandela, le système illustre la solidité de la collaboration européenne : modules cryogéniques conçus par attocube systems AG près de Munich, dispositifs quantiques fabriqués dans la ligne pilote semi-conducteurs de Quandela à Palaiseau, et intégration finale sur le site de Massy. Avec 80 % de ses composants produits en Europe — dont l’ensemble de ses éléments critiques — Lucy illustre la capacité européenne à concevoir et produire des technologies quantiques souveraines.

Accès distant pour accélérer l’adoption

Le système entre dans une phase d’acceptation avant son ouverture aux chercheurs européens début 2026. Afin d’accélérer son adoption et de permettre à la communauté scientifique de se préparer à cette nouvelle capacité, EuroHPC et GENCI ont déjà mis en place un accès distant à d’autres processeurs quantiques photoniques de Quandela hébergés à Massy, via le portail eDARI de GENCI[1].

Les utilisateurs peuvent programmer et exécuter des algorithmes directement via les environnements Perceval et MerLin de Quandela (ce dernier étant dédié au quantum machine learning), garantissant une transition fluide vers l’accès on-premise lorsque Lucy sera pleinement opérationnel.

Par ailleurs, GENCI, le CEA et Quandela proposent déjà des webinaires[2] et des sessions de formation dédiées afin de préparer les communautés d’utilisateurs. Ces initiatives couvrent l’accès aux QPU (Quantum Processing Units) dans le cloud, des cas d’usage en quantum machine learning, ainsi que des sessions pratiques sur Lucy au TGCC. L’objectif est de favoriser une adoption large du calcul quantique dans les milieux académiques et industriels.

Lucy sera la deuxième QPU intégrée à l’environnement de calcul du TGCC, illustrant l’expertise du CEA dans l’intégration de systèmes de calcul complexes à grande échelle. Il s’agit d’une étape majeure vers le calcul quantique hybride pour les applications haute performance.

Strengthening Digital Sovereignty: Inauguration of “Lucy”, the Photonic Quantum Computer at CEA’s TGCC

×

Anne Le Hénanff, Minister Delegate for Artificial Intelligence and Digital Affairs, and Bruno Bonnell, Secretary General for Investment, today inaugurated the Lucy quantum computer. Procured by EuroHPC through GENCI as part of the EuroQCS-France consortium, and co-funded under France 2030’s national quantum strategy, it is hosted at CEA’s Très Grand Centre de Calcul (TGCC). Based on photonic technology developed by Quandela, with cryogenic systems supplied by its German partner Attocube, this new machine is the most powerful of its kind, marking a decisive milestone for the European ecosystem. Coupled with the Joliot-Curie supercomputer, Lucy is now freely accessible to research and industry stakeholders to tackle major scientific challenges.

Bruyères-le-Châtel, 14th April 2026 – Lucy, inaugurated today by Anne Le Hénanff, Minister Delegate for Artificial Intelligence and Digital Affairs, is the world’s most powerful quantum computer based on photonic technology. It is now coupled with the GENCI Joliot-Curie1 supercomputer, hosted and operated by the CEA at the TGCC. This hybrid “HPC-Quantum” architecture combines the computing power of classical high-performance computing with quantum processors, which function as accelerators to solve complex problems. This hybrid approach is central to Europe’s strategy to explore the potential of quantum computing. The system is now freely available to European academic and industrial users, who can submit research projects spanning logistics optimisation, machine learning, materials simulation, and the discovery of therapeutic molecules.

A sovereign quantum capacity at the heart of TGCC

Lucy is built by the Franco-European consortium formed by Quandela and Attocube, illustrating a strategic Franco-German industrial collaboration for the European quantum sector. Produced at Quandela’s facilities in Massy, near Paris, it expands the existing range of computing resources available at TGCC. Procured by EuroHPC Joint Undertaking as part of the EuroQCS-France consortium via GENCI, the system is based exclusively on European technological components. Its deployment under France’s national quantum strategy (HQI programme, France 2030) highlights the dynamism and expertise of French stakeholders while while supporting the competitiveness of the European ecosystem.

Photonics: a credible path to industrial deployment

Photonic technology, which uses light as the carrier of quantum information, is considered one of the most promising approaches for scaling quantum systems to industrial use. Unlike architectures that require processors to operate at temperatures close to absolute zero, photonics enables easier manipulation of qubits and smoother integration into existing data centre infrastructures.

“With Lucy, CEA is turning its long-standing commitment to quantum technologies into concrete reality. From pioneering work on early qubit development within our fundamental research teams — recognised at the highest level in recent years — to the deployment of advanced systems at TGCC, we are demonstrating the strength of an integrated research-to-operations model. This continuity allows us to turn scientific breakthroughs into sovereign industrial capabilities. Lucy is now available to our researchers, as well as to the wider European scientific and industrial community, to help push the boundaries of computing.”

Michaël Krajecki, CEO of GENCI:

“With Lucy, the EuroHPC Joint Undertaking, CEA and GENCI are delivering a unique sovereign hybrid quantum computing capability to European and French scientific and industrial communities. Freely available, Lucy is a pioneering sovereign resource for research and innovation. Powered by photonic technology from Quandela and hosted at TGCC, it brings the industrial scaling of the quantum era closer than ever. This is a major milestone for France and for Europe.”

Niccolo Somaschi, co-foudner and CEO of Quandela:

“With Lucy, we are reaching a major milestone in the industrialization of photonic quantum computing in Europe. Its installation at the TGCC and coupling with the Joliot-Curie supercomputer provide concrete evidence of our ambition: to bring about a sovereign, high-performance quantum capability that is accessible to both researchers and industry. This project is also the result of close cooperation with our German partner attocube, and fully embodies the Franco-German partnership in support of European technological sovereignty. This inauguration shows that cutting-edge quantum technologies designed and manufactured in Europe can already be integrated into the most advanced computing infrastructures to address high-impact scientific and industrial use cases.”

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

“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.”
