• Abstract summary: We demonstrate operation of a rotation sensor based on the $14$N nuclear spins intrinsic to nitrogen-vacancy (NV) color centers in diamond. The sensor employs optical polarization and readout of the nuclei and a radio-frequency double-quantum pulse protocol that monitors $14$N nuclear spin precession.

• Abstract: We demonstrate operation of a rotation sensor based on the $^{14}$N nuclear spins intrinsic to nitrogen-vacancy (NV) color centers in diamond. The sensor employs optical polarization and readout of the nuclei and a radio-frequency double-quantum pulse protocol that monitors $^{14}$N nuclear spin precession. This measurement protocol suppresses the sensitivity to temperature variations in the $^{14}$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 $^{\circ}/\sqrt{\rm{s}}$ (13 mHz/$\sqrt{\rm{Hz}}$), with bias stability of 0.4 $^{\circ}$/s (1.1 mHz).

  We observe the Larmor precession of $15$N nuclear spin depending on the angle between the applied magnetic field and the axis of the nitrogen vacancy center. We propose to utilize the change of the Larmor frequency of the nuclear spins to detect static magnetic fields at high sensitivity.

  Spin-bath interactions are strongly anisotropic, and rapid physical rotation has long been used in solid-state nuclear magnetic resonance. We show that the interaction between electron spins of nitrogen-vacancy centers and a bath of $13$C nuclear spins introduces decoherence into the system. Our findings offer new insights into the use of physical rotation for quantum control with implications for quantum systems having motional and rotational degrees of freedom that are not fixed.
