Description

technical field [0001] The invention relates to the fields of quantum calculation and atomic nucleus simulation, in particular to a quantum calculation-based atomic nucleus simulation method and device. Background technique [0002] The atomic nucleus is an important level of subatomic matter structure. Nuclear physics is a branch of the study of the microstructure of matter established at the end of the 19th century. The release of nuclear energy can provide considerable new energy for human society. Nuclear physics is currently a scientific and technological field with intense international competition. The study of atomic nucleus structure is of great significance. [0003] The traditional method of nuclear simulation based on classical computer and VQE quantum algorithm can achieve the purpose of obtaining the nuclear ground state and ground state energy. However, these methods often have too high computational complexity, especially for the simulation of heavy nuclei...
