Two schemes of remote preparation of a four-particle entangled W state via a six-qubit maximally entangled state
Xin-Wei Zha, Haiyang Song · Physica Scripta · 2011
Two schemes for the remote preparation of a four-qubit W state using a six-qubit maximally entangled state as the quantum channel are presented. The success probability of the preparation is calculated for the two cases. It is worth noting that the probability of success is determined by the sender Alice's measurement. If Alice's measurement is appropriate, the remote preparation can be successfully realized with maximum probability.
