Rubidium Cavity QED

Combining Single Atom Control and Manipulation with Cavity QED in the Strong Coupling regime

Placing N qubit atoms in an optical cavity gives rise to a rich physical setting where highly entangled atomic states naturally arise. However, in most experiments so far, all atoms were permanently coupled to the cavity mode, and could be neither addressed nor read out individually. Our second-generation experiment “Sarocema” combines our successful fiber Fabry-Perot approach with atomic tweezers techniques, to realize a one-dimensional array of individually addressable atomic qubits in the cavity. This opens up the largely unexplored field of quantum simulations with long-range, cavity mediated interactions.
