Abstract
Devices for quantum information computation and communication require the combined use of different quantum systems: photons can transmit informations over large distances, cold trapped atoms can bemanipulated to enable quantum information processing, and atomic ensembles are suited for long-livedquantum memories, as well as non-linear generation of non-classical correlations. Cold atoms are apromising platform to manipulate light, and in this project we will focus on two specific quantuminformation tools: sources of correlated photons and memories, exploiting collective, multimode quantumstates of atomic ensembles. We will address cooperative scattering in large atomic clouds to enhance theseproperties, i.e., we aim at showing how dipole-dipole interactions make it possible to tune both the lifetimeand the optical coherences of the emitted light.
