摘要

The evolution of the entanglement of an initial two-mode squeezed vacuum (TMSV) in correlated noisy channels is investigated. It is shown that the correlated environment is helpful for preserving the entanglement of the initial TMSV.The entanglement period of the initial TMSV depends on the correlation property of the correlated environment.
