“…Since RSP was firstly proposed by Pati and Bennett et al [13,14], it has gained significant attention for the potential applications in quantum distribution computation. Several protocols have been proposed to develop RSP [15][16][17][18][19][20] or JRSP [21,22], involving various entangled states, such as cluster states [23], W states [24], Brown states [25], GHZ states [26] and Einstein-Podolsky-Rosen (EPR) pairs [27]. For example, Zhou et al have presented a general scheme for multiparty JRSP, where the receiver could probabilistically reconstruct the original state by performing unitary operations onto his particles according to the senders' measurement outcomes [28].…”

Joint Remote State Preparation provides a useful way to securely transfer the known quantum states to the distant nodes. However, the limitation of resources often leads to the quantum channels constructed by distributed entangled pairs being incompatible with the transmitted states. In order to overcome this problem, a novel Joint Remote State Preparation protocol was proposed for transmitting general multi‐qudit states over quantum networks, providing a promising pathway to utilise the available Einstein‐Podolsky‐Rosen (EPR) channels with different levels. Several scenarios under noisy environments were discussed and some properties of the fidelity when transmitting the multi‐qudit state were demonstrated. It was demonstrated that both the prepared state and the kind of the noises could restrict the number of the participant nodes. Our scheme leverages the existing quantum resources, which addresses the issue of insufficient entanglement resources. This approach is easily adaptable to other quantum network structures, offering a potential solution for constructing a universal quantum network.
