      abstract = {Optically addressable defect spins in semiconductors are  promising candidates for quantum memories. Merging spins  and mechanics into hybrid quantum systems provides a route  to engineering quantum registers and transducers. However,  precise control of such systems requires a comprehensive  understanding of each component as well as their mutual  interactions. In this thesis we explore the imaging of  surface acoustic wave phonons and their coupling to  electron spins. We then present an overview of spin-strain  coupling in silicon carbide divacancies, followed by  fabrication and microwave characterization of Gaussian  surface acoustic wave resonators on commercial wafer-scale  substrates with a piezoelectric aluminum nitride film. The  resonator's mechanical modes are measured optically using  the point defect charge state’s sensitivity to electric  fields that are piezoelectrically induced. Additionally,  local strain and dynamic lattice distortions from standing  waves produced by interdigitated transducers are imaged  with nanometer-scale resolution using X-ray diffraction  microscopy. Finally, we demonstrate all-optical detection  of acoustic paramagnetic resonance with spin ensembles.  Furthermore, we show magnetically forbidden Rabi  oscillations for full ground-state spin control and use  these resonant, coherent interactions with phonons for  quantum sensing.},
