Abstract
Section titled āAbstractāI will describe our experiments driving spin and orbital resonance of diamond nitrogen-vacancy (NV) centers using the gigahertz-frequency strain oscillations produced within a diamond bulk acoustic resonator. Strain-based coupling between a resonator and a defect center takes advantage of intrinsic coupling mechanisms while maintaining compatibility with conventional magnetic and optical techniques. We demonstrate coherent spin control over both double quantum (Īm=Ā±2) and single quantum (Īm=Ā±1) transitions, providing opportunities for quantum sensing and protection of spin coherence. At cryogenic temperatures, we use orbital-strain interactions driven by a diamond acoustic resonator to study multi-phonon orbital resonance of a single NV center.
