摘　　要：铌酸锂材料具有宽的透光范围和高的非线性光学、电光、声光、热光系数,且化学性能稳定,是理想的光子集成芯片的衬底材料。在量子光学领域,人们已经发展出一系列铌酸锂基集成器件,能够实现光子态的高效率产生、调控、频率转换、存储和异质集成的单光子探测,有望实现全集成的频率态操控、确定性多光子态制备和单光子间相互作用,最终形成全功能集成的有源光量子芯片,推动量子物理基础研究和光量子信息应用发展。文章回顾了基于铌酸锂基量子集成的研究进展,并对其在未来光量子信息时代的机遇与挑战进行探讨。Lithium niobate has a wide light transparency range,high nonlinear-optic,electro-optic,acousto-optic and thermo-optic coefficients,as well as stable chemical properties,which makes it an ideal substrate material for photonic integration.In the field of quantum optics,a series of lithium niobate based integrated devices have been developed,which can enable the highly efficient generation,manipulation,frequency conversion,quantum storage and integrated single-photon detection of photon states,and has the potential for fully integrated photon frequency manipulation,deterministic multi-photon state generation and photon-photon interaction.This may push forward the development of fully functional integrated quantum optical circuits,which will further promote fundamental quantum physics studies and practical applications of quantum information technology.This paper will review the progress of lithium niobate based quantum integration,and its future opportunities and challenges.
