General quantum simulator based on cold atom system

Disclosed is a general quantum simulator based on a cold atom system, the alkali metal atom hyperfine structure Zeeman magneton multi-energy-level system is used for simulating a multi-dimensional physical and chemical model, and the specific physical and chemical model can be mapped to the specific energy level of atoms by the focusing mapping relation. Any coupling between two energy levels can be realized by regulating and controlling the intensity, the frequency and the phase of the microwave signal generated by the arbitrary waveform device. In combination with a plurality of arbitrary waveform generators, arbitrary regulation and control of a multi-dimensional system can be realized. According to the regulation and control requirements of a specific physical system, the general quantum simulator can be realized by regulating microwave signals; the invention has the advantages that the method is universal, the invention is not limited to specific physical and chemical models, quantum simulation of any mu
