摘要
We suggest theoretically the possibility to transmit information through a decohering quantum channel employing Glauber's coherent states. In fact, we study the dynamics of quantum correlations of two-mode entangled bipartite coherent states in the presence of the amplitude damping effect. In addition, we examine the quantum correlations based on quantum discord, which is a powerful key source in quantum information processing.
