Efficient schemes of joint remote preparation with a passive receiver via EPR pairs
Song-Ya Ma, Cong Gao, Ming‐Xing Luo · Chinese Physics B · 2015
Novel schemes are put forward to execute the joint remote preparation of an arbitrary two-qubit state with a passive receiver via EPR pairs as the entangled channel. Compared with the previous protocols, the required multi-particle measurement is simplified and the classical communication cost is reduced. When the number of senders increases, the advantage is more evident. It means that the proposed schemes are more efficient in practice.
