摘　　要：研究了自旋1/2系统的量子态控制问题。首先通过分析量子系统状态的轨迹演变误差,利用模糊开关控制对所研究的量子系统状态进行模糊控制,其次根据量子克隆的思想,对控制后的量子态进行复制,进而对克隆得到的量子态进行测量,将测量结果反馈到控制系统中,最后在一个给定的误差范围内得到系统控制的目标态。This paper mainly researches the control problem of spin-1/2 systems. First of all, through the analysis of the trajectory evolution of the quantum state of the system, fuzzy switch laws are utilized to control the studied quantum states. Then, according to the idea of quantum cloning, the quantum state of the controlled system is cloned which is measured later and its measurement result is feedback to the previous system. Finally, the target state is obtained within a given error range.
