摘要：

In this paper, two schemes for joint remote preparation via linear optics elements are proposed. Firstly, we propose a scheme for joint remote preparation of an arbitrary two-photon state via linear-optical elements by using a five-qubit cluster state as the quantum channel. Then, the JRSP protocol of an arbitrary three-photon state via linear-optical elements, which was rarely considered in previous papers, is investigated. All the senders share the information of prepared state. The senders transform the quantum channel to the target quantum channel according to their information of prepared state, and the receiver can prepare the original state by performing corresponding operations on his entangled particles. Our scheme has advantage of transmitting less particles for joint remote preparing an arbitrary two-qubit state. Moreover, it is more convenience in application since it only requires linear-optical elements for joint remote preparation.
