Abstract: | For two parties sharing the original state, a scheme for remote preparation of the two-particle entangled state by three partial
two-particle entangled states as the quantum channel is presented, and then directly generalize the scheme for remotely preparing
a multipartite GHZ-class state for M senders. It is shown that the receiver can obtain the unknown state with certain probability under the condition that only
and only if all the senders collaborate with each other. The N-particle projective measurement and the von Neumann measurement are needed in our scheme. The probability of the successful
remote state preparation and classical communication cost are calculated. |
