| Abstract: | Cavity quantum electrodynamics (CQED) experiments realize the simplest matter–field system: a single atom coupled to a single field mode containing only a few photons. On the one hand, these experiments can be used to test fundamental features of the quantum world. On the other hand, they implement elementary quantum logic components: qubits and quantum gates. We present here a review of the CQED experiments performed at Ecole Normale Supérieure with circular Rydberg atoms and superconducting millimeter-wave cavities. |
