Item POVM no contexto de eletrodinâmica quântica de cavidades(Universidade Federal de Goiás, 2017-03-13) Assis, Rogério Jorge de; Almeida, Norton Gomes de; http://lattes.cnpq.br/3182841849332242; Almeida, Norton Gomes de; Villas-Boas, Celso Jorge; Almeida, Agnaldo Rosa deIn 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.
