Increasing Spin Coherence in Nanodiamond via Dynamic Nuclear Polarization

ORAL

Abstract

Nanodiamonds are of interest for quantum information technology, as metrological sensors, and more recently as a probe of biological environments. Here we present results examining how intrinsic defects can be used for dynamic nuclear polarization that leads to a dramatic increase in both T$_{1}$ and T$_{2}$ for $^{13}$C spins in nanodiamond. Mechanisms to explain this enhancement are discussed.
