Two-dimensional, atomically-thin, materials have received enormous interest as a result of their unique mechanical, electrical and optical properties. Particularly exciting are the transition metal dichalcogenides – atomically-thin semiconductors that possess an electronic band gap in the visible. Although these materials have been investigated for applications in opto-electronics, not much work has focused on these systems as a platform for quantum photonics and quantum optics. In this talk I will describe two approaches that leverage atomically thin semiconductors, and other two-dimensional materials, assembled in layered van der Waals heterostructures for applications in these areas. In the first part of the talk I will describe the unique photophysical properties of quantum emitters hosted by single layer transition metal dichalcogenides. I will describe our recent efforts to control the confined excitons via the application of electric fields and strain. Finally, I will report on the observation of the coherent evolution of quantum emitters in the insulator hexagonal boron nitride.
