主　　题：W state GHZ state entanglement transfer dissipation 

摘      要：We investigate the influence of the initial mixture of qubits and the dissipation on the entanglement transferfrom three-qubit Greenberger-Horne-Zeilinger (GHZ) and W state fields to three matter qubits,which are trapped inthree spatially separated *** find that at gt≈11.07,the entanglement transfer can be almost complete nomatter what state the qubits are initially prepared *** the dissipation is taken into account,we tind that thespontaneous emission plays the similar role to the cavity damping in the entanglement transfer,and the decay rate ofthe GHZ state is larger than that of the W state.
