在这项工作中，我们提出了一种新的和有效的信息处理方式，多方控制的联合远程状态准备（MCJRSP），通过控制网络中的多个代理将量子信息从多个代理传输到一个远程接收器。首先提出了一种利用Greenberg-Horne-Zeilinger纠缠态实现任意单粒子态MCJRSP的方案，然后推广到任意两粒子态的情形.值得注意的是，不同于传统的联合远程状态准备，所需的状态不能被恢复，但所有的代理一起协作。此外，还计算了成功概率和经典信息代价，揭示了成功概率与所用纠缠的关系，对多粒子态的情况进行了简单的推广，最后在全光框架下分析了方案的实验可行性。我们认为，我们的建议可能是重要的远距离通信在未来的量子网络。
In this work, we present a novel and efficient information-processing way,multiparty-controlled joint remote state preparation(MCJRSP), to transmit quantum information from many senders to one distant receiver via the control of many agents in a network. We firstly put forward a scheme regarding MCJRSP for an arbitrary single-particle state via Greenberg–Horne–Zeilinger entangled states, and then extend to generalize an arbitrary two-particle state scenario. Notably, different from conventional joint remote state preparation, the desired states cannot be recovered but all of agents collaborate together. Besides, both successful probability and classical information cost are worked out, the relations between success probability and the employed entanglement are revealed, the case of many-particle states is generalized briefly, and the experimental feasibility of our schemes is analysed via an all-optical framework at last. And we argue that our proposal might be of importance to long-distance communication in prospective quantum networks.
