• 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.

We demonstrate that the FCM-based QEM technique allows for reasonable improvement of the expectation values of single- and two-qubit gates based quantum circuits.

  We introduce a quantum version for the statistical complexity measure, in the context of quantum information theory, and use it as a signalling function of quantum order-disorder transitions. We apply our measure to two exactly solvable Hamiltonian models, namely: the $1D$-Quantum Ising Model and the Heisenberg XXZ spin-$1/2$ chain. We also compute this measure for one-qubit and two-qubit reduced states for the considered models, and analyse its behaviour across its quantum phase transitions for finite system sizes as well as in the thermodynamic limit by using Bethe ansatz.
