摘　　要：主要研究量子导引在一些具体量子通讯过程中的作用,通过计算通道量子态的导引及其在具体量子通讯过程中的保真度,比较二者间的对应关系,证实远程量子态制备和量子隐形传态过程中,通道量子导引对保真度有正向的影响.The effect of quantum steering in specific quantum communication process is studied in this paper. By calculating the steering of channel quantum state and its fidelity in the specific quantum communication process,and comparing the corresponding relationship between the steering and fidelity of the channel quantum state,it is confirmed that channel quantum steering has a positive impact on fidelity in the process of remote quantum state preparation and quantum teleportation.
