Entropic and information inequality for nonlinearly transformed two-qubit X-states
V. I. Man'ko, R. S. Puzko
The entropic and information inequalities for two qubit X-states transformed by the nonlinear channels are given in explicit form. The subadditivity condition and nonnegativity of…

Deformed entropic and information inequalities for X - states of two-qubit and single qudit states
V. I. Man'ko, L. A Markovich
The q-deformed entropies of quantum and classical systems are discussed. Standard and q-deformed entropic inequalities for X - states of the two-qubit and a state of single qudit w…

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…
