N2 - We investigate the influence of the initial mixture of qubits and the dissipation on the entanglement transfer from three-qubit Greenberger-Horne- Zeilinger (GHZ) and W state fields to three matter qubits, which are trapped in three spatially separated cavities. We find that at gt ≈ 11.07, the entanglement transfer can be almost complete no matter what state the qubits are initially prepared in. When the dissipation is taken into account, we and that the spontaneous emission plays the similar role to the cavity damping in the entanglement transfer, and the decay rate of the GHZ state is larger 'than that of the W state.
