Tomographic Discord and Quantum Correlations for System of Qubits    [PDF]

V. I. Manko, Anatoli Yurkevich
The difference of quantum mutual information for bipartite system of qubits and minimum taken with respect to local unitary transformation group is introduced as a characteristic of quantum correlations.The two qubits example (and specifically the two qubits X state) is studied in some details.
