Dissertação (Mestrado em Física) - Universidade Federal de Goiás, Goiânia, 2017.http://repositorio.bc.ufg.br/tede/handle/tede/7238In this work it is proposed a simplified scheme to unambiguously discriminate between one of two nonorthogonal cavity field states. This scheme, which is based on POVM - positive operator valued measure, uses one three-level atom as the ancilla to obtain information on the cavity field state, the target. The efficiency of this scheme in discriminating the two quantum states is analy zed by comparing the maximum theoretical success probability with the maximum success probability possible to our case.application/pdfAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Discriminação de estados quânticosMedição quântica geralEletrodinâmica quântica de cavidadesQuantum states discriminationGeneral quantum measurementCavity quantum eletrodynamicsFISICA GERAL::FISICA CLASSICA E FISICA QUANTICA; MECANICA E CAMPOSDissertação
