FRESNEL: Engineering a Neutral Atom Quantum Computer — •Guillaume Villaret for the FRESNEL collaboration — Pasqal SAS, 7 Rue Léonard de Vinci, 91300 Massy, France

Based on the work from the group of A. Browaeys and T. Lahaye at Institut d'Optique, quantum startup PASQAL developed and produced a first generation of commercial QPUs called FRESNEL. These devices allow analogical computations on arrays of up to 100 Rydberg atoms. Interfaced through a cloud access, these QPUs already proved their reliability. They allowed quantum software engineers to propose and demonstrate applications for solving hard combinatorial optimisation problems, non-linear differential equations and classifying sets of graphs using machine learning. Some of these QPUs are currently under construction in two HPC centers in Jülich, Germany and in Bruyères-le-Châtel, France. This represents a big step forward in term of reliability for neutral atoms QPUs, and more generally for cold atoms technologies which require a high level of engineering. We will give an overview of the technical building blocks of the FRESNEL products, discuss its capabilities for analog-based quantum computing in the NISQ era, and present the latest results.
