“…In the past decades, quantum information technology [1][2][3][4][5] has received much attention and the anticipation to realise the application of quantum communication and quantum computing. By exploiting the non-locality of entanglements, quantum information processing (QIP) plays a vital role in quantum communication and it has branched out many applications, such as quantum cryptography [6], quantum dialogue [7], quantum teleportation (QT) [8], superdense coding [9,10], quantum secret sharing [11,12] and remote state preparation (RSP) [13][14][15][16][17][18][19][20]. In QT, there is nobody who knows the transmitted state and it can securely teleport the unknown state.…”

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.
