3D Uniform Manipulation of NV Centers in Diamond Using a Dielectric Resonator Antenna

Abstract

Ensembles of nitrogen-vacancy (NV) color centers in diamond hold promise of ultraprecise magnetometery competing with SQUID detectors. By utilizing advantages of dielectric materials such as very low losses for electromagnetic field and therefore possibility to create high quality factor resonators with strong concentration of the field in it we implemented a dielectric resonator antenna for coherent manipulation of large ensemble of NV centers in diamond. We reached average Rabi frequency of 10 MHz in the volume of 7 cubic millimeters with standard deviation less than 1% at moderate pump power. This result passes the way to improve sensitivity of cutting edge NV based magnetometers by two orders of magnitude practically reaching SQUID level of sensitivity.
