GYROSCOPES BASED ON NITROGEN-VACANCY CENTERS IN DIAMOND

摘要

A solid-state gyroscope apparatus based on ensembles of negatively charged nitrogen-vacancy (NV−) centers in diamond and methods of detection are provided. In one method, rotation of the NV− symmetry axis will induce Berry phase shifts in the NV− electronic ground-state coherences proportional to the solid angle subtended by the symmetry axis. A second method uses a modified Ramsey scheme where Berry phase shifts in the 14N hyperfine sublevels are employed.

1. A method of inertial sensing, comprising:
(a) providing a diamond sensor with a plurality of nitrogen-vacancy centers; (b) exposing the diamond sensor to a magnetic field along nitrogen-vacancy center axes; (c) rotating the diamond sensor to generate geometric phase shifts in the nitrogen-vacancy centers; (d) detecting the geometric phase shifts; and (e) reading information from the geometric phase shifts.
