Abstract  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.
Keywords:  teleportation      N-particle entangled W state      entanglement swapping      unitary transformation
