量子计算机的算力可体现为量子计算机可实现并行计算, Grover算法(Quantum Search Algorithm)是量子计算领域的主要算法之一。Grover算法是由Grover于1996年提出的平方根加速的随机数据库量子搜索算法,旨在利用量子计算机进行比经典计算机更快的数据搜索。在数据库足够混乱且没有具体的数据结构限定的条件下,Grover算法可以快速解决...
Grover 算法,有时也称为量子搜索算法(quantum search algorithm),指一种在量子计算机上运行的非结构化搜索算法,是量子计算的典型算法之一。 它具有 O(N) 的复杂度,其中 N 表示搜索空间元素的个数,相较于经典搜索 O(N) 具有多项式量级的加速。 概括来说,Grover 算法的总体框架是 构造一个易于实现的操作 G ,...
Quantum Computation and Quantum Information 第六章 Grover 算法是一种量子搜索算法,说到搜索算法,了解一些经典算法的旁友肯定会想到二分搜索(binary search)算法,二分搜索在有序数组中查找某一特定数据可以做到对数级别的复杂度,但如果目标是无序的呢? 假设下面这个例子:你要在N个一毛一样,完全区分不了的快递中找...

The quantum circuit has been devised, while numerical simulation and experiment on a heart disease dataset have been conducted programming within the Qiskit framework. Both have verified the feasibility of the algorithm. Moreover, an application of classification has been developed based on the trained...
Grover's quantum algorithm can solve this problem much faster, providing a quadratic speed up. Quadratic here implies that only about N evaluations would be required, compared to N.Outline of the algorithmSuppose there are N=2n eligible items for the search task and they are index by assigning...
