在这项工作中，我们提出了一种使用六个 EPR 类型对作为共享量子资源来实现任意三量子位状态的联合远程准备的方案。通过确定准备器的正确测量基础和接收器的正确辅助辅助单一变换/恢复操作，我们的方案适用于当要准备的状态的所有系数和 EPR 类型对都是复数时的最一般情况。发现总成功概率仅取决于接收者和准备者之一之间共享的 EPR 类型对的“较小”系数。
In this work, we propose a scheme to realize a joint remote preparation of an arbitrary three-qubit state using six EPR-type pairs as the shared quantum resource. By determining the right measurement bases for the preparers and right ancilla-assisted unitary transformation/recovery operations for the receiver, our scheme applies to the most general case when all the coefficients of the state to be prepared and the EPR-type pairs are complex. The total success probability is found to be dependent only on the “smaller” coefficients of the EPR-type pairs shared between the receiver and one of the preparers.
