Quantum Correlations in non-Markovian Environments
arXiv:1006.3943 · doi:10.1016/j.physleta.2010.08.060
Abstract
We have studied the analytical Markovian and non-Markovian dynamics of quantum correlations, such as entanglement, quantum discord and Bell nonlocalities for three noisy qubits. Quantum correlation as measured by quantum discord is found to be immune to death contrary to entanglement and Bell nonlocality for initial GHZ- or W-type mixed states.
