Teleportation of Multipartite State via W State
Zheng‐Yuan Xue, You-Min Yi, Zhuo‐Liang Cao · Communications in Theoretical Physics · 2006
A scheme of teleporting a multi-particle state via W state is presented. The W class states serve as quantum channels. After the sender operates both Von Neumann measurements and Bell-state measurements and then inform the receiver her results, the receiver can reconstruct the original state by corresponding unitary transformation. The probability of successful teleportation is also obtained. Special example of four-particle state is discussed in detail.
