| 摘 要： | 以一般形式的三粒子的W态作为量子通道来实现未知单粒子的概率的受控远程传输。该计划的特征是两者之间远程传输的实现依赖于第三者（Charlie）的同意与否，她可以作为一个控制者参与量子远程传输的整个过程。另外，通过基本的逻辑操作，我们组建了有效的量子逻辑网络图来实现该新计划。

| Abstract: | We discuss the scheme for probabilistic and controlled teleportation of an unknown state of one particle using the general three-particle W state as the quantum channel. The feature of this scheme is that teleportation between two sides depends on the agreement of the third side (Charlie), who may participate the process of quantum teleportation as a supervisor. In addition, we also construct efficient quantum logic networks for implementing the new scheme by means of the primitive operations. |
