Item Modelo de Jaynes-Cummings completo de dois fótons: estudo e aplicações(Universidade Federal de Goiás, 2009-02-20) SOUZA, Alexandre Divino de; AVELAR, Ardiley Torres; http://lattes.cnpq.br/5732286631137637; BASEIA, Basilio; http://lattes.cnpq.br/5804506385505435In this work we have studied the two photon Jaynes-Cummings model to describe the interaction of a three-level atom in the configuration with a single-mode of a cativy-field. We have used the effetive and full microscopic Jamiltonian approach to compare the results obtained in these tow descriptions. We employed the two-photon Jaynes-Cummings model int the full microscopic Hamiltonian context to implement schemes to quantuam entanglement swapping, for approximate and conditional quantuam teleportation for an unknown atomic state, for a superposition of zero- and two photon states. Both schemes were implemented using no measurement in the Bell base states.Item Operador Deslocamento Condicional: Geração de Estados e Medida da Função de Wigner(Universidade Federal de Goiás, 2006-03-24) SOUZA, Simone Ferreira; BASEIA, Basilio; http://lattes.cnpq.br/5804506385505435We present a feasible proposal for the construction of the conditional displacement operator using a Kerr medium between two beam splitters fed from coherent states highly excited. The device allows the implementation of the generation of a new class of states the quantized electromagnetic field (arbitrary superpositions of states with states moved) and the measurement of the Wigner function for arbitrary states. The application special case of the number of states and study their nonclassical properties were also considered.
