Abstract
Section titled âAbstractâUnderstanding spin physics and controlling solid-state spins at nanometer length scales is of crucial importance in modern physics research. Because of the atomic-scale dimensions, long coherence time, and optical readout, Nitrogen-Vacancy centers (NV centers) in diamond have become prominent for exploring topics in nanoscale spin physics. In this thesis, two questions are investigated using single NV centers: what mechanisms limit the control and measurement of geometric phase of a single solid-state spin qubit, and whether it is feasible to detect electron spin resonance in submicron volumes from copper-ion-labeled molecules. We have obtained limits on the fidelity of geometric phase gates, and showed using newly developed quantum sensing techniques that we are indeed able to detect such extremely weak signals, down to the single spin limit. Our results with NV centers in measuring single electron spins opens the door to a variety of applications of NV center magnetometry in interdisciplinary topics such as research on the dynamics of protein molecules with copper ion labels.
