提出了一种利用七比特纠缠态作为量子信道实现五方双向控制联合远程态制备的新协议。研究表明，两个相距遥远的节点在管理者的控制下，可以同时确定地与另一个节点进行状态交换，并且没有控制者的许可，交换是不可能成功的。我们的方案只使用了泡利操作和单量子比特测量，因此在现有技术范围内，五方方案是可行的。
A new protocol for implementing five-party bidirectional controlled joint remote state preparation is proposed by using a seven-qubit entangled state as the quantum channel. It can be shown that two distant senders can simultaneously and deterministically exchange their states with the other senders under the control of the supervisor, and it cannot be succeed without permission of the controller. Only pauli operation and single-qubit measurement are used in our scheme, so the scheme with five-party is feasible within the reach of current technologies.
