摘要：
A scheme for entanglement teleportation of a completely unknown state so as to incorporate a multipartite entangled state as the quantum channel is proposed. By deriving the relations of separabilities for joint measurements and for corresponding unitary operations, it is found that an inseparable quantum channel always leads to a total teleportation of entanglement. This paper gives an example of an inseparable quantum channel with each triad in three-qubit entanglement.
