This project addresses bipartite entanglement and blockade effects in cold and dilute atomic clouds scattering light. These systems exhibit long-range interactions which result in extended collective modes, despite the two-atom interaction being weak. Our goal is to investigate the potential of these systems to generate entanglement at the scale of the system, as well as blockade effects like those encountered in systems of Rydberg atoms (yet considering transitions with the ground state). Our study will address not only the appearance of these effects due to long-range interactions, but also their experimental signatures (collective Rabi oscillations, etc).
