    "abstract": "We have developed a full quantum microscopic theory to analyze the time\nevolution of transversal and longitudinal components of an exciton-single\nphoton system coupled to bulk acoustic phonons. These components are subjected\nto two decay processes. One is radiative relaxation and the other is\npure-dephasing due to exciton-phonon interaction. The former results in a decay\nwith an exponent linear to time, while the latter causes a faster initial decay\nthan the radiative decay. We analyzed the dependence of the components on the\nduration of the input one-photon pulse, temperature, and radiative relaxation\nrates. Such a quantitative analysis is important for the developments of\natom-photon interfaces which enable coherent transfer of quantum information\nbetween photons and atomic systems. We found that, for a GaAs spherical quantum\ndot in which the exciton interacts with bulk phonons, the maximal probability\nof the excited state can be increased up to 75 %. This probability can be\nconsidered as the efficiency for quantum information transfer from photon to\nexciton.",
