金刚石氮空穴(Nitrogen-vacancy,NV)色心固态自旋量子陀螺仪是利用量子自旋态敏感角速度的新型传感器,具有高灵敏、小体积等突出优点,可很好地满足特殊领域对高精度和小体积方面的需求,但目前仍处于理论研究阶段。本项目引入声子场操控技术,开展NV量子自旋态的声子辅助操控机理、固态自旋操控和测量方法、声子辅助固态自旋角速度敏感原理以及荧光信号微腔增强方法等关键问题研究,建立基于声子辅助操控机理的固态自旋角速度精密测量方法,研制兼具高精度和小型化潜力的固态自旋角速度测量实验装置。该研究不仅可以完善现有NV色心固态自旋量子态操控理论和方法,还有助于发展新颖的角速度测量方法和技术,这对于打破西方国家的技术封锁和垄断,推进我国新原理陀螺仪国产化具有重要意义。
英文摘要
Diamond Nitrogen-vacancy (NV) center solid-state spin gyroscope, a new type of angular velocity sensor that uses quantum spin states to sense angular velocity, has outstanding advantages such as high sensitivity and small volume. It can satisfy the requirements of accuracy and volume in special applications for gyroscopes. However, it is still in the stage of theoretical research. This project introduces phonon field control technology and conducts research on key issues such as the phonon-assisted regulation mechanism of NV quantum spin states, solid-state spin control and measurement method, the angular velocity sensitivity principle based on phonon-assisted solid-state spin and the fluorescence signal enhancement mechanism of microcavity. In this project, the solid-state spin angular velocity precision measurement method based on phonon-assisted regulation mechanism is established, and the experimental device of a solid-state spin angular velocity measurement device with potential of high accuracy and small size is developed. This research can not only improve the existing theory and method of manipulation of the NV center solid state spin quantum state, but also contribute to the development of novel angular velocity measurement methods and technologies. It is of great significance for breaking the technical blockade and monopoly of western countries, promoting production localization of new principle gyroscopes in China.
