Building neutral-atom quantum processors — •Pierre-Antoine Bourdel for the Pasqal team — Pasqal SAS, 7 rue Léonard de Vinci, 91300 Massy, France

In the past years, neutral atoms have entered the quantum computing race. Quantum startup PASQAL has stemmed from the group of A. Browaeys and T. Lahaye, who pioneered trapping single atoms in arbitrary, defect-free and reconfigurable tweezer patterns. In this highly scalable platform, excitation to Rydberg states enables controlled interactions between atoms, and entanglement generation. Such platform has already demonstrated quantum simulations in a regime out of reach with current classical approaches. Regarding quantum computation, applications have been proposed and demonstrated for solving hard combinatorial optimisation problems, non-linear differential equations and classifying sets of graphs using machine learning. We will give an overview of the technical building blocks of our platform at PASQAL, discuss its capabilities for digital and analog-based quantum computing in the NISQ era, and present the last results that we have achieved with our neutral atoms quantum processors.
