Abstract

The invention discloses a data identification method and device based on a quantum computer and a computer readable storage medium. The method comprises: performing quantization on to-be-identified data to generate input quantum bits suitable for a quantum computer; performing quantum calculation on the input quantum bit by using a pre-trained quantum neural network to obtain a multi-dimensional output quantum bit; determining the total number of target quantum bits in the multi-dimensional output quantum bits according to the classification category numerical value of the to-be-identified data, and performing quantum state coding on each label according to the total number to obtain a quantum state coding label set; measuring each target quantum bit to obtain corresponding state information; and matching a corresponding target label in the quantum state coding label set based on the state information to serve as an identification result of the to-be-identified data, thereby realizinga full-linearization calculation task of data classification and identification in the quantum computer, and realizing a full-quantization calculation process without assistance of a traditional computer.
