摘要：
We investigated the quantum entanglement transfer through two independent spin chains with phase shift. The initial target states (vertical bar 01 > + vertical bar 10 >) / root 2 or its mixed state is shown to be more suitable for quantum correlation transfer in this system. Generating a phase shift by the Aharonov - Casher effect partly improves the amplitude of the entanglement, whereas it is unfavorable for prolonging the survival time of quantum entanglement. We compared and analyzed the effects of spin chains parameters on quantum discord and quantum entanglement. The result indicated that the quantum entanglement is more robust than quantum discord in the two parallel XXZ spin chains. (C) 2015 Elsevier GmbH. All rights reserved.
