Quantum and classical correlations in a classical dephasing environment
چکیده انگلیسی

We calculate the non-Markovian dynamics of quantum correlations, including entanglement and discord, and classical correlation in a two-qubit system with Ornstein–Uhlenbeck noise and discuss the relations in these correlations. Itʼs found that the initial-state parameters and the non-Markovian properties play an important role in these dynamics behaviors.

Research highlights
► The critical transition time can be greatly prolonged in local noises.
► The non-Markovian properties are not always benefit to discord in global noise.
► Quantum discord can be greatly amplified or protected, etc., in global noise.
