Quantum electrodynamic in cavity

Scientific activity

The CQED team at the LKB is working towards the realization of quantum simulations using circular Rydberg atoms. These giant atoms have particularly long lifetimes, enabling simulations to be carried out over extremely long timescales, while retaining the strength of the interatomic interactions at the heart of existing Rydberg atom simulators.

Three experimental set-ups are used to produce ordered arrays of circular Rydberg atoms trapped in optical tweezers, to prepare circular Rydberg levels in Strontium atoms, and to obtain circular Rydberg atoms protected from spontaneous emission, to achieve lifetimes of several minutes.
