The quantum amplitude amplification is the generalization of quantum Grover search algorithm. In this strategy, the Grover iteration has been replaced by two different quantum amplitude amplification operations. This makes it possible to collapse the system with probability 1, in other words, with certainty. The measurement operation in this scheme is only used to cancel the phase factor. Finally, one can use the admissible control to drive the system from the eigenstate to the target state and the control task is accomplished.

量子幅值放大是Grover迭代思想的一般化,该控制方案中采用两种不同的量子幅值放大操作替换了Grover迭代,使得期望本征态的概率幅的模在经过一定次数的迭代之后精确的等于1,然后借助于测量来消除相位因子,使系统的波函数确定性的塌缩到期望的本征态,最后再借助幺正演化,将系统从本征态控制到目标态,实现期望的控制任务。
