提出了一种利用6量子位最大纠缠态的双向远程状态制备方案。在本文中，我们提出了一个新的协议，它允许两个远程方在第三方远程方的控制下同时和确定性地交换他们的状态。这样，如果没有控制器的许可，它就不能成功。基于von Neumann测量和Bell状态测量，Alice可以将任意的单量子比特状态传输给Bob，而Bob可以通过监督者Charlie的控制将任意的单量子比特状态传输给Alice。
It is presented that a bidirectional remote state preparation scheme uses six-qubit maximally entangled state. In this paper we propose a new protocol which allows two distant parties to simultaneously and deterministically exchange their states under controling of a third remote party. In such a way, it cannot be successful without permission of the controller. Based on the von Neumann measurement and Bell state measurement, Alice can transmit an arbitrary single qubit state to Bob, while Bob can transmit an arbitrary single qubit state to Alice via the control of the supervisor Charlie.
