Integer decomposition optimization method and system based on Grover quantum computing search algorithm

Abstract

The invention belongs to the technical field of quantum computing, and particularly relates to an integer decomposition optimization method and system based on a Grover quantum computing search algorithm. The method comprises the following steps: simulating a quantum bit line, and enabling an input ground state to be converted into a superposed state through Hadamard transformation; converting aninteger decomposition problem into an optimization problem, expressing integers to be decomposed and prime factors of the integers by using a binary system, and constructing a binary multiplication table; obtaining a binary multiplication equation set according to the binary multiplication table, and simplifying the equation set by introducing constraint conditions; setting iteration conditions, converting the simplified equation into a Boolean logic relationship, and constructing a quantum black box; reversing the target state amplitude relative to the average amplitude by using the unitary matrix, and increasing the probability of searching the target item; and changing the probability of searching the target item through repeated iteration until the probability of searching the target item is optimal. A good calculation effect can be achieved, an acceleration effect is particularly obvious in a large-scale search problem, and the method and the system have a good application value.
