Analytically Computable Symmetric Quantum Correlations

arXiv:1903.07318 · doi:10.1002/andp.201800178

Abstract

Analytic quantifiers of the symmetric quantum discord for two-qubit X type states and block-diagonal states and the symmetric measurement induced nonlocality for any two qubit states are established on the basis of the quantum skew information.
