Leveraging Silicon Carbide Defects to Build Quantum Information Hardware
Silicon carbide has been an attractive commercial host of defect emitters called color centers featuring fiber-compatible single photon emission, long spin-coherence times and nonlinear optical properties. Integration of color centers with nanophotonic devices has been a challenging task, but significant progress has been made with demonstrations up to 120-fold resonant emission enhancement of emitters embedded in photonic crystal cavities. A novel direction in overcoming the integration challenge has been the development of triangular photonic devices, recently shown to preserve millisecond-scale spin-coherence in silicon carbide defects. Triangular photonics has promising applications in quantum networks, integrated quantum circuits, and quantum simulation.

In this webinar hosted by the Nanophotonics Technical Group, Marina Radulaski from the University of California, Davis, will discuss how open quantum system modeling provides insights into polaritonic physics achievable with realistic device parameters through evaluation of cavity-protection, localization and phase transition effects. The mapping of these dynamics to gate-based quantum circuits opens the door for quantum advantage in understanding cavity quantum electrodynamical (QED) effects using commercial Noisy Intermediate-Scale Quantum (NISQ) hardware.
