From free-evolution to tomographic representation
Sergio Cordero, Ramón López-Peña, Eduardo Nahmad-Achar +3
We use the free evolution propagator to determine the quantum probability representation (i.e., the general expression of the tomogram) of any one-dimensional system described by a…
Dynamic violation of Bell's inequalities in the angular momentum representation
J. A. López-Saldívar, O. Castaños, S. Cordero +2
A parametrization of density matrices of dimensions in terms of the raising and lowering angular momentum operators is established together with an implicit connect…
Extremal Density Matrices for Qudit States
Armando Figueroa, Julio A. López-Saldívar, Octavio Castaños +1
An algebraic procedure to find extremal density matrices for any Hamiltonian of a qudit system is established. The extremal density matrices for pure states provide a complete desc…
