Dynamics of quantum correlations under correlated noisy channels
Original language description
This study investigates the dynamical aspects of quantum correlations under two uses of noisy channels with memory. In this article, considering a family of pure entangled states, we study the quantum correlation in terms of entanglement and measurement-induced nonlocality (MIN) (based on trace distance and fidelity) when the consecutive actions of a quantum channel on the sequence of qubits have partial classical correlations. It is found that the quantum correlations monotonically decrease as the correlation strength increases, which indicates that the correlation measures strongly depend on both the noise parameter and the correlation strength of the channel. The results also illustrate that the memory effects offer more robustness against the considered noise. These findings give us insights into exploiting the resource content of the quantum state to achieve quantum advantages.
