Abstract
The solid state single photon source is fundamental key device for application of quantum communication, quantum computing, quantum information and quantum precious metrology. After years of searching, researchers have found the single photon emitters in zero-dimensional quantum dots (QDs), one-dimensional nanowires, three-dimensional wide bandgap materials, as well as two-dimensional (2D) materials developed recently. Here we will give a brief review on the single photon emitters in 2D van der Waals materials. We will firstly introduce the quantum emitters from various 2D materials and their characteristics. Then we will introduce the electrically driven quantum light in the transition metal dichalcogenides (TMDs)-based light emitting diode (LED). In addition, we will introduce how to tailor the quantum emitters by nanopillars and strain engineering, the entanglement between chiral phonons (CPs) and single photon in monolayer TMDs. Finally, we will give a perspective on the opportunities and challenges of 2D materials-based quantum light sources.
