Joint remote preparation of an arbitrary three-qubit state via EPR-type pairs

Q. Q. Chen, Y. Xia and Nguyen Ba An

In this work, we propose a scheme to realize a joint remote preparation of an arbitrary three-qubit state using six EPR-type pairs as the shared quantum resource. By determining the right measurement bases for the preparers and right ancilla-assisted unitary transformation/recovery operations for the receiver, our scheme applies to the most general case when all the coefficients of the state to be prepared and the EPR-type pairs are complex. The total success probability is found to be dependent only on the “smaller”___ coefficients of the EPRtype pairs shared between the receiver and one of the preparers.
