Abstract: The invention pertains to the field of gyroscopes, in particular—to quantum gyroscopes. The invention provides a gyroscope employing an ensemble of NV-centers in diamond, which includes a diamond plate, a source of green light, an optical system for directing the green light to the diamond plate, a photodetector for registering fluorescence of the color centers in the diamond plate, optical elements that direct the fluorescence from the diamond plate to the photodetector, a source of microwave radiation, a source of radiofrequency radiation, and a source of constant magnetic field, the gyroscope being different from the prior art in that it comprises an energy-efficient antenna that creates a strong longitudinal homogeneous field in the entire volume of the diamond plate with the possibility of frequency adjustment, as well as a system for locking the frequency of the microwave field to that of the transition in the color centers.
