NMR dynamics of quantum discord for spin-carrying gas molecules in a closed nanopore
M. A. Yurischev
A local orthogonal transformation that transforms any centrosymmetric (CS) matrix of fourth order to the X form is found. A picewise-analytic-numerical formula Q=min{Q_π/2,Q_θ,Q_0}…

On the quantum discord of general X states
M. A. Yurischev
Quantum discord Q is a function of density matrix elements. The domain of such a function in the case of two-qubit system with X density matrix may consist of three subdomains at m…
