Abstract
We demonstrate the operation of a rotation sensor based on the nitrogen-14 (<sup>14</sup>N) nuclear spins intrinsic to nitrogen-vacancy (NV) color centers in diamond. The sensor uses optical polarization and readout of the nuclei and a radio-frequency double-quantum pulse protocol that monitors <sup>14</sup>N nuclear spin precession. This measurement protocol suppresses the sensitivity to temperature variations in the <sup>14</sup>N quadrupole splitting, and it does not require microwave pulses resonant with the NV electron spin transitions. The device was tested on a rotation platform and demonstrated a sensitivity of 4.7°/<math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><msqrt><mi mathvariant="normal">s</mi></msqrt></mrow></semantics></math> (13 mHz/<math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><msqrt><mtext>Hz</mtext></msqrt></mrow></semantics></math>), with a bias stability of 0.4 °/s (1.1 mHz).
