Progress for high photon collection of color centers in quantum materials

ORAL

Abstract

Color centers in materials have attracted enormous amount of attention due to their interesting quantum properties for quantum computation, quantum optics[1], and quantum sensing applications[2]. The most notable research has been focused on NV centers, SiV centers in diamond, divacancy in silicon carbide, and etc. There is also an increasing focus on defects, exciton physics in 2D materials. These collections of point-like entities share common optical technique in studies. Thus, efficient collection of each associated photons serves as the ultimate bottle neck in all applications. In this work, we present an effective approach to tackle this fundamental limit and use NV center as an example for its application[3,4].
