"Probabilidades negativas" e tomografia de Qubits
(Universidade Federal de São Carlos, 2007-03-28)
In this dissertation we approached the tomography of discrete systems, understood as the representation
and the reconstruction of states. For the tomography we used distribution functions
of symmetrical pseudo-probabilities. ...
