Cavity Quantum Electrodynamics with Tin Vacancy Centers in Diamond
ORAL
Abstract
Diamond color centers are promising qubit candidates for scalable quantum networks given their optical interface and coherent spin properties. In particular, the negatively charged tin-vacancy center (SnV) is of great interest given its compatibility with nanophotonic integration, robustness towards electric field noise to the first order, and spin coherence at 1.7K. In this talk, we discuss characterization of diamond nanophotonic cavities with enhanced and tunable outcoupling achieved by utilizing silicon carbide waveguide probes. We then explore demonstrations of Purcell enhancement with implanted SnV centers. Our work demonstrates the potential of integrated methods towards nanophotonics characterization and the promise of SnV center quantum nodes for scalable networks.
