    • Correlacões quânticas: medidas e simetrias 

      Souza, Simone Ferreira (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 17/06/2011)
      In this thesis, we explore two sort of quantum correlations: entanglement and quantum discord. We present a geometric method to identify and measure the degree of entanglement based on symmetries of vectors and matrices ...

    • Estados parcialmente emaranhados em comunicação quântica 

      Gomes, Raphael Fortes Infante (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 16/03/2012)
      In this master s thesis we approach the entanglement between quantum states as a resource to be used in the transmission of quantum information, particularly in quantum teleportation. Our focus was directed toward the study ...

    • Processos Paramétricos em eletrodinâmica quântica de cavidades. 

      Villas-Bôas, Celso Jorge (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 02/03/2004)
      In this thesis we study the interaction between an atom and a cavity mode submitted to linear and parametric amplifications. The evolution operator of the system was derived through the technique of time-dependent ...

    • Comunicação quântica baseada no teletransporte em variáveis contínuas 

      Luiz, Fabrício de Souza (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 12/12/2014)
      In this Thesis we study in details one of the most astonishing application of quantum mechanics which totally departs from our common sense: quantum teleportation in continuous variables. We present a review of the postulates ...
