Teleportation of N-particle entangled W state via entanglement swapping
Teleportation of N-particlstate via entanglemente entangled W swapping

A scheme for teleporting an unknown N-particle entangled W state is proposed via entanglement swapping. In this scheme, N maximally entangled particle pairs are used as quantum channel. As a special case, the teleportation of an unknown four-particle entangled W state is studied.
