<p>A novel scheme enabling joint remote state preparation among multiple parties is proposed, based on a specific Greenberger–Horne–Zeilinger-class (GHZ-class) chain network. All the participants including the intermediate nodes possess partial knowledge of the target state and collaborate to transmit their measurement outcomes to the remote receiver via classical communication. Based on these collective results, the receiver can apply appropriate unitary operations to reconstruct the desired target state. Different from previous remote state preparation approaches, our scheme employs multiple different non-maximally entangled GHZ states to form a chain channel, which greatly broadens its applicability and reduces the requirement for the quantum channel. Moreover, our approach achieves full multiparty participation by sharing the information of the target state among all the participants. Notably, some participants not only act as the information owners but also serve as the relay nodes, thereby extending the scope of distributed quantum information. In addition, we demonstrate the feasibility of our protocol through an explicit simulation experiment on IBM Quantum (IBMQ) Composer platform.</p>
