  • Gyroscopes based on nitrogen-vacancy centers in diamond
    Patent number: 9689679
    Abstract: 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.
    Type: Grant
    Filed: October 2, 2014
    Date of Patent: June 27, 2017
    Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
    Inventors: Dmitry Budker, Micah Ledbetter, Kasper Jensen, Andrey Jarmola
