Computers revolutionized our society in ways that could not even be imagined at their advent in the mid-20th century. Quantum computers hold similar promises. One of the key challenges is the development of single-photon emitters (SPE) that can be useful for a variety of quantum-enabled technologies. An extensive search is ongoing for such single-photon emitter sources, and none have yet shown all the desired properties for technological applications. We propose to investigate SPE that is needed for the emerging quantum-enabled technological world. Advances in the field of nanotechnology, lithography, and stamping techniques have enabled the fabrication of various devices with 2D Transition Metal Dichalcogenides (TMDCs) materials with tunable physical properties. The ability to stack monolayers of dissimilar TMDCs provides great flexibility in creating designer structures for a given application. There are recent reports establishing a strong, anti-bunched, stable and narrow linewidth emission from these materials. We aim to study the prospects of SPE in these materials.
