| Cavity quantum electrodynamics, which describes the physics of a spin and a spring in interaction, can serve as a model to analyse many recent quantum optics and solid state experiments. Ions in traps, Bose Einstein condensates in optical lattices, superconducting circuits coupled to microwaves are among the many domains in which the ideas of Cavity QED are encountered under various disguises. The talk will review some of these experiments and discuss the connexions between them as well as perspectives opened for future work. |
