French National Quantum Update: April 2026

France’s quantum ecosystem continues to advance across policy, business, and research, with coordinated efforts to strengthen technological sovereignty, expand global partnerships, and accelerate the path to real-world applications.On the policy front, France is reinforcing Europe’s push for sovereign quantum infrastructure through initiatives such as the inauguration of the Lucy quantum computer under the EuroHPC Joint Undertaking. Hosted at the TGCC and supported by national agencies including CEA and GENCI, the system reflects a broader strategy to integrate quantum computing with high-performance computing (HPC) resources. International engagement remains a priority, with French companies and institutions deepening ties across Asia, including South Korea and Japan, signaling a coordinated diplomatic and industrial approach to quantum collaboration.In business and industry, France is backing its ambitions with significant capital and commercialization strategies. Public and private investments — estimated at around €500 million — are positioning French startups as credible competitors in the global quantum race. Companies such as Quandela are deploying photonic quantum systems integrated with HPC infrastructure, while C12 has outlined a roadmap targeting fault-tolerant quantum computing by 2033. Meanwhile, Pasqal continues to expand internationally, including enabling access to its neutral-atom systems in Canada through partnerships that combine quantum and classical computing resources. France is also moving aggressively on cybersecurity preparedness, with plans for post-quantum cryptography adoption by 2030.Research efforts remain focused on overcoming core technical barriers. Advances in quantum algorithms, such as tensor network-based pre-optimization techniques, are addressing longstanding challenges like barren plateaus in variational quantum computing. These developments aim to improve the scalability and practical performance of quantum systems, particularly in areas where classical simulation becomes inefficient.The ecosystem is further supported by a steady cadence of events and knowledge exchange. Industry gatherings such as Pasqal Thoughts 2026 and international conferences on cavity quantum electrodynamics highlight the growing convergence of academia, industry, and government. These forums reflect how purely theoretical research is moving toward operational quantum systems integrated into existing computing environments.It is important to note that this summary captures only a portion of recent developments. France’s quantum community remains highly active, and this is not an exhaustive account of all activity across the nation.EuroHPC JU Inaugurates a Quantum Computer in France, Strengthening Europe’s SovereigntyThe 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). Quandela Expands in South Korea: From Research to Real-World Quantum ImpactQuandela took part in the French President’s state visit to South Korea, marking 140 years of diplomatic relations between the two countries. On this occasion, Quandela reaffirmed its commitment to building a long-term partnership with South Korea as a key hub for quantum technologies, with a focus on accelerating research, talent development, and the industrialization of photonic quantum computing.Exchange of Views on Quantum Computing with French Startup Quobly at the French Embassy in Japan Deputy Director NEGORO Makoto (Professor), along with Professor OIWA Akira of the University of Osaka’s SANKEN (and concurrently affiliated with QIQB), visited the Embassy of France in Japan (Minato-ku, Tokyo) for a meeting with startup company Quobly. The meeting was made possible with the cooperation of Business France, the French Trade and Investment Agency, which supports the international expansion of French companies and foreign investment into France. Quobly’s expressed interest in QIQB’s activities prompted this meeting at the Embassy and served as an opportunity to exchange views on quantum computing.France bets €500 million that quantum computing is the tech race Europe can finally winEurope has spent a decade watching American and Chinese companies capture every major technology wave, cloud, mobile, social, AI. Quantum computing may be the exception. A cluster of French startups, backed by €500 million in government funding and underpinned by some of the world’s strongest physics research, is positioning France as a serious contender in a race where legacy advantages count for remarkably little.Quandela Deploys Photonic Quantum Computer Integrated with HPC SystemLucy, inaugurated today by the Minister Delegate for Artificial Intelligence and Digital Affairs, Anne Le Hénanff, is the world’s most powerful quantum computer based on photonic technology. It is now coupled to GENCI’s Joliot-Curie supercomputer , hosted and operated by the CEA at the TGCC.C12 Unveils Roadmap, Targets Useful Fault-tolerant Quantum Computing by 2033C12, a Paris-based quantum computing company developing processors based on carbon nanotube spin qubits, unveiled its technology roadmap towards commercial fault-tolerant quantum computing. The roadmap outlines four generations of systems, from Aïdôs (2027) to Panopeia (2033), designed to scale quantum processors from early logical qubits to utility-scale quantum computers.Canada Gains Access to Pasqal Quantum Systems via PINQ²PINQ² (Digital and Quantum Innovation Platform) today announced it has become the exclusive Canadian distributor of Pasqal’s neutral atom quantum computing technology. The partnership, enabled by DistriQ’s purchase of a 100-qubit quantum processing unit from Pasqal, makes PINQ² Canada’s only not-for-profit platform combining IBM superconducting and Pasqal neutral atom quantum technologies with classical HPC infrastructure – enabling the hybrid quantum-classical workflows that most real-world research and commercial applications require. Quantum computing: A tech race Europe could win?In a lab on the western edge of Paris, where the River Seine flows wide and trams slide past glass-fronted buildings and blossoming cherry trees, a technician called Rémi makes some adjustments with a spanner.The machine, a cascade of gold and silver-coloured cylinders descending through a cloud of wires, is a cryostat, its purpose: to create an ultra-cold environment.Europe Preps for Post-Quantum ComputingFrance appears to be at the forefront of European efforts to prepare for the arrival of quantum computing and its potential impact on cybersecurity, with an aggressive 2030 transition timeline for the implementation of post-quantum cryptography.Pre-optimization of quantum circuits, barren plateaus and classical simulability: tensor networks to unlock the variational quantum eigensolverVariational quantum algorithms are practical approaches to prepare ground states, but their potential for quantum advantage remains unclear. Here, we use differentiable 2D tensor networks (TN) to optimize parameterized quantum circuits that prepare the ground state of the transverse field Ising model (TFIM). Our method enables the preparation of states with high energy accuracy, even for large systems beyond 1D. We show that TN pre-optimization can mitigate the barren plateau issue by giving access to enhanced gradient zones that do not shrink exponentially with system size. We evaluate the classical simulation cost evaluating energies at these warm-starts, and identify regimes where quantum hardware offers better scaling than TN simulations.Qubit Pharmaceuticals to Collaborate With The Centre For Quantum Technologies in Singapore to Advance Quantum Algorithms For Drug DiscoveryQubit Pharmaceuticals, a deeptech company specializing in the discovery of new drug candidates, today announced a strategic research collaboration with the Centre for Quantum Technologies (CQT) in Singapore to develop and utilize novel quantum algorithms for molecular discovery. This two-year collaboration combines Qubit Pharmaceuticals’ expertise in quantum chemistry and sampling techniques with CQT’s extensive skills in quantum computing, circuit design, and experimental implementation. The goal is to bridge the gap between advanced quantum chemistry and Monte Carlo methods and practical drug discovery applications.Pasqal Showcases Quantum Progress at 2026 EventPasqal, a leader in neutral‑atom quantum computing, hosted its flagship event Pasqal Thoughts 2026 on World Quantum Day at Le Cercle d’Aumale in Paris.
