First, one. analyzes the eigenstates-from reachable sets and seeks the one which the target state belongs to. Then using the Grover iteration to amplify the probability amplitude of the desired eigenstate (the modul square of which is the probability of the corresponding eigenstate that the system will collapse to when it is measured). By measuring, the system will then collapse to the desired eigenstate with a probability of almost unity. Finally, one can use the admissible control to drive the system from the eigenstate to the target state.

该策略的核心思想是对本征态能控的系统,通过分析控制目标态与本征态的关系,寻找给定目标态所属的本征态可达集,然后利用量子非结构化搜索的Grover算法,将任意给定的系统初始态经过一定次数的Grover迭代,放大该本征态所对应的概率幅(概率幅的模方对应测量时波函数塌缩到对应本征态的概率),然后对迭代后的态进行一次测量操作,使系统以接近1的概率塌缩到所需的本征态(前面分析得到的本征态可达集所对应的本征态),最后用容许的控制将系统从该本征态控制到期望的目标态。
