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 ...
