Single-photons versus weak-coherent pulses for quantum memories — •Tom Schmit¹, Luigi Giannelli¹, Stephan Ritter², Gerhard Rempe², and Giovanna Morigi¹ — ¹Theoretische Physik, Universität des Saarlandes, 66123 Saarbrücken, Germany — ²Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Strasse , 85748 Garching, Germany

We theoretically analyse the absorption of light incident on a cavity by a single atom within the resonator. We model the atom with a three-level Λ-system and assume that one transition interacts with a single cavity mode while the other is driven by an external laser field. We further include the resonator’s and the atom’s losses. We then compare the fidelity of absorption when the incident light is a weak coherent pulse and when it is a single photon.
