Local-available quantum correlation swapping in one-parameter X states

Abstract: Although introduced originally for entanglement, quantum repeaters and swapping protocols have been analyzed for other quantum correlations (QC), such as quantum discord. Introduced by Mundarain and Ladr\'on de Guevara, local-available quantum correlations (LAQC) are a promising yet understudied quantum correlation. Recently, Bellor\'{\i}n et al. obtained exact analytical results for the LAQC quantifier of general 2-qubit X states. Starting from those previous results, we analyzed the LAQC swapping for five families of one-parameter 2-qubit X states. As expected, we find that if the initial state and the one used for the projective measurement are correlated, the final state will have non-zero LAQC.
