标记态的任意相位旋转不能用于Grover的量子搜索算法

Arbitrary phase rotation of the marked state can not be used for Grover's quantum search algorithm

Gui Lu Long, Wei Lin Zhang, Yan Song Li, Li Niu

摘要:

澄清了一种误解,即标记态的任意相位旋转和Grover搜索算法中平均运算的逆运算可以用来构造效率较低的量子搜索算法.标记态相位的$π$旋转不仅是效率的选择,而且在Grover的量子搜索算法中也是至关重要的。实验结果还表明Grover量子搜索算法具有较好的鲁棒性。

英文摘要:

A misunderstanding that an arbitrary phase rotation of the marked state together with the inversion about average operation in Grover's search algorithm can be used to construct a (less efficient) quantum search algorithm is cleared. The $π$ rotation of the phase of the marked state is not only the choice for efficiency, but also vital in Grover's quantum search algorithm. The results also show that Grover's quantum search algorithm is robust.
