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.
