LKB - Cavity Quantum Electrodynamics

Cavity Quantum Electrodynamics

Our research activity focuses on the manipulation of Rydberg atoms in three different experimental configurations: coupled to microwave photons stored in high-finesse Fabry-Pérot cavities, prepared in a gas of ultracold atoms, or manipulated as individual quantum systems. Our goals include fundamental tests of quantum mechanics, the realisation of quantum simulations, or the demonstration of quantum sensing.
