摘　　要：量子模拟技术通过调控原子体系构建人造晶格,可用于模拟微观世界的多体物理现象。概述了以超冷原子光晶格、莫尔超晶格与量子点超晶格为代表的人造晶格构建量子模拟器的方法及其研究成果,讨论了原子体系下不同类型人造晶格量子模拟平台的特点和优势。然而,由于材料和技术上的限制,目前固态量子模拟平台还未能实现室温工作且大规模集成生产。硅纳米晶体管局域沟道内具有量子点特性的杂质原子为解决这一问题提供了可能。最后,总结了人造晶格量子模拟器所面临的挑战,并给出了后摩尔时代基于杂质原子量子点阵列构建硅基量子模拟器的发展思路。Quantum simulation technology,by regulating the atomic system to construct artificial lattices,can be used to simulate multi-body physical phenomena in the microscopic world.The methods and research achievements of constructing quantum simulators using artificial lattices represented by ultracold atomic optical lattices,Moirésuperlattices and quantum dot superlattices are overviewed.The characteristics and advantages of different artificial lattice quantum simulation platforms under the atomic systems are discussed.However,due to material and technical limitations,the solid-state quantum simulation platforms can't work at room temperature and integrate production at large-scale.The dopant-atom-induced quantum dots within the confined channels of silicon nanoscale transistor provides a potential solution to solve this problem.Finally,the challenges of artificial lattice quantum simulators are summarized and the development ideas for silicon-based quantum simulators constructed by dopant-atom quantum dot arrays in the post-Moore's era are presented.
