Development and Prospect of Inertial Measurement Technology Based on Diamond Nitrogen Vacancy Color Centers: A Review

The negatively charged nitrogen-vacancy (NV-) color center in diamond has been widely used in the physical measurement of magnetic field, electric field and temperature because it has the advantages such as stable level-structure, long coherence time at room temperature and easy operation. The inertial measurement technique based on diamond NV- centers is one of the emerging directions in the field of inertial measurement technique based on quantum effect of atomic spin. In this review, firstly, the structure and properties of diamond NV- color center are introduced. Then the basic principle of geometric phase of quantum system and the inertial measurement scheme and system of NV- color center geometric phase are described. Thirdly, the development status of diamond NV- centers inertial measurement technology at home and abroad is introduced. Finally, the future development trend of diamond NV- color centers inertial measurement technology is prospected.
