Engineering, Control, and Integration of 2D Based Quantum Defects for Integrated Quantum Photonics

In recent years, the discovery of defect-based SQEs in 2D materials, most notably WSe2 and h-BN, have emerged as promising candidates for highly bright and pure generation of on-demand single-photons. In this talk, I will discuss our experiments that shed light on the origin of SQEs and resulted in a novel method to site-specifically engineer SQEs in 2D materials with high spatial resolution, yield, purity, and record-breaking working temperatures. Additionally, I'll discuss several advances in photonic integration that resulted in the development of a 2D-compatible photonic platform capable of >46% on- chip collection efficiency and > 95% single-photon purity at room temperature.
