dc.description.abstractIn this thesis, we propose a realizable experimental scheme to prepare a superposition of the vacuum and one-photon states using a typical cavity QED-setup. This is different from previous schemes, where the superposition state of the field is generated by resonant atom-field interaction and the cavity is initially empty. Here, we consider only dispersive atom-field interaction and the initial state of the cavity field is coherent. Then, we determine the parameters to prepare the desired state via atomic post-selection. We also include the effect of cavity losses and detection imperfections in our analysis against which this preparation of the optical qubit in a real Fabry-Perot superconducting cavity is robust. In addition, we show that this scheme can be used for the preparation of other photon number Fock state superpositions. In short, our task is achieved with high fidelity and a post-selection probability within experimental reach. With the same scheme, we propose to cool the cavity field to its ground state starting from a thermal distribution by a dispersive atom-field coupling followed by an atomic post-selection. We also analyze the effect of the cavity and atomic losses. The proposed experiment can be realized with real parameters with high fidelity.
