A quantum algorithm of multislice method

Abstract

Multislice method is widely used to simulate the elastic interaction of an electron beam with matter in electron microscopy. In this paper, we propose a quantum algorithm of multislice method. With the use of quantum circuit this quantum version of multislice method costs less storage space and less runtime than the classical algorithm by taking advantage of the feature of quantum computing. We have used a classical supercomputer to simulate a quantum circuit, and successfully carried out the quantum multislice computation and obtained the expected result on a virtual quantum circuit, which proves the feasibility and correctness of the quantum algorithm. This work demonstrates the potential application prospect of quantum computing to the research of computational physics as a good example.
