英文摘要： Quantum enhanced metrology is an emerging new research direction. Predictably, it will be very important potential application in areas such as the quantum communication and quantum computation, quantum frequency scale, quantum positioning, and quantum imaging. Exploration and development the new principle and new technology on the basis of the quantum physics is not only a new technical challenges, and to promote some disciplines development such as quantum optics, atomic optics, atomic physics and so on, which has far-reaching significance. Based on these potential academic value and application background, the combination of quantum physics and precision measurement are high attention by scientists. Applicant presents the research on quantum correlation enhanced metrology based on the research accumulation, academic foundation and the recent research progress of all into consideration. This project will be based on the quantum theory of interaction between light and atoms, and develops the new precision measurement exploration and research based on quantum correlation as the core principle. Phase sensitive precision measuring scheme is put forward on the basis of the quantum enhancement. New methods of phase measurement accuracy to break through the restriction are found in principle. The success of this project will promote quantum optics, atomic optics, precision measurement physics and the development of quantum information science and other fields.
