Zusammenfassung: | Novel schemes are put forward to execute the joint remote preparation of an arbitrary two-qubit state with a pas- sive 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. |
