摘要

In this paper,we accomplish the teleportation of an unknown three-particle maximally entangled W state by using a spin-path entangled quantum channel which may be realized experimentally based on the advanced theory and technique in Bose-Einstein condensate(BEC)of molecule,micro-fabricated wave guide and simple quantum logic gate.Similarly,we can make an arbitrary n-particle entangled Greenberger-Horne-Zeilinger(GHZ)state(n≥4)teleported through this kind of quantum channel.It may have important applications due to its resource-economic and practical features.
