干涉技术在显微、全息、传感、导航、精确制导等领域所展现出的强大技术威力是尽人皆知的。对干涉测量精度与灵敏度的不断追求已导致了近代光学多个分支学科的诞生。特别是近年来，随着人们对微观量子世界的科学认知水平和技术控制能力的不断擢升,一个以量子光学与原子光学为基础，量子技术为牵引力的前沿方向- - 基于光子与原子量子操控的量子精密测量研究（Quantum Metrology）正在兴起。本项目的立项正是顺应这一国际前沿发展趋势，利用我们团队在相关领域所积累的强力理论优势以及近年来发展的实验基础，开展基于原子系综量子操控的量子精密测量的研究与探索，开拓以量子干涉技术为核心的相关量子技术。本项目的成功不仅将推动量子光学、原子光学以及量子信息科学等相关学科领域的进一步发展，而且将为量子精密测量研究在量子操控的意义上提供全新的思路与技术途径。

It has been well-known that interferometry exhibits a great power of technology in the areas of microscope, holography, sensor, navigation, inertial guidance, and so on.The pursuit for the precision and sensitivity of interfrometry has led to a number of branches in the modern optics.In particular,with the recent development of quantum science and rising ability of quantum control technology, a new frontier, following quantum optics and atom optics, quantum metrology based on quantum manipulation of photons and atoms is emerging.The proposed project, targeting the development of the frontier on our advantage in theory and recent progress in experiment, will explore quantum metrology based on quantum manipulation of atomic ensembles, and develop the related quantum technologies including quantum interfrometry. The success of the project not only will lead to the new development of the areas including quantum optics，atom optics and quantum information, but also provide completely new scientific ideas and technical approaches for quantum metrology in the context of quantum manipulation.
