HQI logo

The HQI project aims at the creation of a hybrid computing platform that couples several quantum processors with Joliot-Curie supercomputer hosted at TGCC (High Performance Computing Center) of the French Commission for Atomic Energy and Alternative Energies (CEA), as well as the development of an academic and industrial research program with user enablement.

HQI’s main objective is to make access to quantum computing easier for a wide community of research institutions, industries and startups, to identify, develop and test new use cases. This initiative is serving the needs of the users willing to evaluate free of charge, on public infrastructure, the potential of quantum computing for their applications and develop international collaborations to foster open research. 

Its overall budget is €72.3M, covering both equipment and research work during six years (2022-2028).

Our role

Bull is highly involved in HQI’s R&D stream coordinated by the CEA. Our work is mainly focused on the development of a pilot of a converged hybrid classic/ quantum platform, integration of the multiple QPUs and evolution of the emulation platform based on Bull’s Qaptiva machine. 

Bull is also contributing to the development of physics applications on the quantum computers, with a specific focus on appropriate format and discretizations, management of faults and errors and topic of hybridization of classical and quantum EDP solvers. 

The project is led by the Quantum Computing R&D team based in Les Clayes-sous-Bois (France) in collaboration with HPC Hardware experts. At the beginning of 2026, Bull’s Quantum Consulting team joined the project and has been also contributing to the development of the Maison du Quantique Occitanie, a regional hub in the South of France, dedicated to the development of industrial research and research projects in hybrid quantum computing.
