摘　　要：随着拓扑相和拓扑材料的发现,拓扑已经从数学概念变成现代凝聚态物理学一个重要的前沿方向。尽管越来越多的拓扑材料被预言,在人造可控量子体系中进行拓扑量子模拟仍会对材料的理解和制备起到极大的促进作用。文章简单总结了基于冷原子和超导量子比特系统开展拓扑量子模拟的进展。介绍了这两种量子系统的特点,以及相应的拓扑量子模拟实验方法,还分析了这两种体系在实验手段和物理原理上的联系。Since the discovery of topological phases and materials, topology, as a mathematical concept, has inspired great interest in modern condensed matter physics. Although many types of topological materials have been predicted and discovered, their simulation in controllable artificial quantum systems will greatly help our understanding and further study of such materials,and various experimental methods have already been developed. In this paper we briefly summarize the progress of quantum simulation in cold atoms and superconducting qubit systems. We describe the characteristics of different quantum systems and the corresponding experimental methods for their simulation. In addition, we also summarize the relationship between the experimental schemes and physical principles of the two systems.
