| Resumen en inglés | Local available quantum correlations (LAQCs), as defined by Mundarain et al., are analytically determined for Bell Diagonal states. Using the Kraus operators formalism, we analyze the dissipative dynamics of 2-qubit LAQCs under Markovian decoherence. This is done for Werner states under the depolarizing and phase damping channels. Since Werner states are among those that exhibit the so called entanglement sudden death, the results are compared with the ones obtained for Quantum Discord, as analyzed by Werlang et al., as well as for entanglement, i.e. Concurrence. The LAQCs quantifier only vanishes asymptotically, as was shown to be the case for Quantum Discord, in spite of being lower |
