Tackling Interface Challenges for Near-Surface Quantum Emitters in Diamond

Learn about quantum sensing challenges and solutions in this technical lecture exploring near-surface quantum emitters in diamond. Discover how color centers in diamond function as solid-state quantum sensors capable of detecting nanoscale changes in magnetic fields, temperature, and strain at room temperature. Explore the key interface challenges faced by these quantum defects, including spin decoherence and light trapping within crystal structures. Follow detailed discussions on recent research developments, including radiative emission modeling, nanophotonic component integration for improved light extraction, and surface analysis techniques aimed at enhancing spin coherence. Presented by Jennifer Choy, Dugald C. Jackson Assistant Professor at UW-Madison's Department of Electrical and Computer Engineering, drawing from her extensive background in quantum magnetometry and inertial sensing from MIT and Harvard University.
