We will present the work done on a new generation of quantum processors that we are developing at PASQAL, a spin-off company of the Institut d'Optique, which is building neutral atom quantum computers. This machine incorporates optical tweezer technology in a cryogenic environment. We have recently incorporated high numerical aperture optics that allow us to trap hundreds of single atoms in the tweezer array. In addition to that, we are demonstrating improved vacuum-limited lifetime compared to room temperature setups. This prototype represents a significant milestone, bringing us closer to the realisation of a neutral atom processor with more than a thousand qubits.
