New entropic inequalities for qubit and unimodal Gaussian states
J. A. López-Saldívar, O. Castaños, M. A. Man'ko +1
The Tsallis relative entropy measures the distance between two arbitrary density matrices and . In this work the approximation to this quantity w…

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…

Entropy-energy inequalities for qudit states
Armando Figueroa, Julio López, Octavio Castaños +3
We establish a procedure to find the extremal density matrices for any finite Hamiltonian of a qudit system. These extremal density matrices provide an approximate description of t…
