Expérimental
Cold atoms coupled to photons are a promising platform for quantum information, computation and communication. The light radiated by a quantum emitter, such as an atom, generally features quantum correlations and squeezing , which are at the heart of many applications in quantum technologies. While antibunching is the key ingredient for single photon sources, squeezed light is an important tool for sub shot noise quantum sensing. The goal on our experiment is to detect antibunching and squeezed light with many quantum emitters in a 3D system . This will be implemented and studied on our cold atom experiment, taking advantage of our experience with generating clouds of cold atoms with large optical thickness, a prerequisite for this project. The current collaboration with the group of Arno Rauschenbeutel will finally help to determine the experimental parameters needed to observe this antibunching effect.
