摘　　要：用光镊形成光阱囚禁单个原子、用激光将单个原子冷却到基态形成超冷原子、将超冷原子相干合成单个超冷分子、将单原子分子重排串成丰富多样的超冷单原子分子阵列,这就构成了精密相干可控的多粒子量子系统,为多种前沿科学研究与技术发展提供难得的量子平台。文章介绍近年来在单原子量子态高保真操控、异核原子量子纠缠、原子-分子耦合态相干控制、单个超冷分子的相干合成、异核原子阵列确定性制备等方面所取得的最新研究结果;对未来在多体物理、超冷化学、精密测量、量子模拟、量子计算等方面的发展前景进行了展望。Trapping single atoms with optical tweezers,cooling the atoms to the ground state to form ultracold atoms,coherently controlling them to form single ultracold molecules,then rearranging them into a rich and diverse array of ultracold single atoms and molecules,all of these steps create a precise and coherently controllable multi-particle quantum system,and provide a rare quantum platform for a variety of frontier scientific research and technology development.This article reviews the latest progress in the study of ultracold single atom and molecule arrays.Recent results on high fidelity control of quantum states of single atoms,heteronuclear quantum entanglement,coherent control of atom-molecule states,coherent formation of a single molecule,and deterministic preparation of heteronuclear atom arrays are outlined.The future prospects in many-body physics,ultracold chemistry,precision measurement,quantum simulation and quantum computation are presented.
