Probabilistic Teleportation of the Three-Particle W Entangled State via Nonmaximally Entangled Cluster state

摘要

A scheme of teleportation of the three-particle W entangled state via nonmaximally entangled Cluster state is proposed in the paper. Firstly, an auxiliary particle is introduced, and two particles in quantum channel carry out CNOT operation on it; secondly, distorted state caused by nonmaximally entangled quantum channel can be recovered by constructing unitary transform matrix; finally, the teleportation of entangled W state can be achieved with probability. The Bell measurement can be reduced and the resource of quantum channels can be saved for using one entangled Cluster state as quantum channel.
