Heterogeneously Integrated Photonic Systems for Quantum Science

Photonic integration of solid-state quantum emitters offers a promising route to scalable on-chip quantum technologies for sensing and simulation. Achieving this goal requires combining material platforms that provide both strong opto-electronic tunability and robust qubit coherence. In this talk, I will discuss our recent progress in characterizing and enhancing the coherence of emerging solid-state spin-qubit systems, as well as in identifying materials with large electro-optic and piezoelectric nonlinearities at cryogenic temperatures, where many quantum platforms operate. These results provide a pathway toward realizing heterogeneously integrated quantum devices for simulation and sensing of nanoscale chemical and physical processes.
