Quantum and classical correlations in a classical dephasing environment

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. It's found that the initial-state parameters and the non-Markovian properties play an important role in these dynamics behaviors. (C) 2011 Elsevier B.V. All rights reserved.
