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…

Geometric properties of qudit systems
J. A. López-SaldÃvar, O. Castaños, S. Cordero +2
We discuss in general how to geometrically visualize a qudit system, with a particular interest in thermal states. The principle of maximum entropy is used to study the geometric p…

Dynamic violation of Bell's inequalities in the angular momentum representation
J. A. López-SaldÃvar, 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…
