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.

Introduced by Mundarain and Ladrón de Guevara, local-available quantum correlations (LAQC) are a promising yet understudied quantum correlation. Recently, Bellorín et al. obtained exact analytical results for the LAQC quantifier of general 2-qubit X states.

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

Flipping qudits: Extending the Bit-Flip Channel to higher-dimensional systems
We present three possible extensions of the bit-flip channel to qutrit systems based on the diverse interpretations of the channel. Also, we extended them to higher-dimensional qudit systems, formulat...

formulating different versions of dit flip channels. Finally, we studied their impact on the Negativity, as an entanglement measure, of qubit-qutrit and 2-qutrit Werner states. In doing so, we showed the inequivalence of these versions as they affect in very distinct ways the states entanglement.
