| 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 |
