    • 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 ...

    • Geometria e simetrias do emaranhamento 

      Braga, Helena Carolina (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 20/05/2011)
      In the present work we present a geometric method to identify and measure the degree of entanglement of a two-qubit state. It is based on writing a map of the system state, from a non-unitary transformation. By introducing ...

    • Teorema de Schur no plano de Minkowski e caracterização de hélices inclinadas no espaço de Minkowski 

      Ramos, Luciano de Melo (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, , 27/06/2013)
      A classical theorem of differential geometry of curves in Euclidean space is the Schur's Theorem, that was proof by A. Schur in 1921, when both curvatures agree pointwise [3]. The proof in the general case was proved in ...
