The long lifetimes and strong dipole-dipole interactions of circular Rydberg atoms make them particularly appealing for the realization of quantum simulations. A recently-developed hybrid platform, that combines them with ancillary atoms excited to standard Rydberg levels, enables their local non-destructive measurement and manipulation, opening the way to the operation of the quantum simulator. The intern will participate in the transformation of the existing room-temperature setup into a cryogenic setup where we will fully benefit from the long lifetimes of circular states. We will use the new setup to demonstrate quantum simulations in a subsequent doctoral work.
