■ Abstract
Single photons play a crucial role in a wide range of applications, such as quantum computing, quantum
communications, and precision sensors. Among the various physical systems, solid-state materials show great
promise as host materials for single-photon emitters due to their scalability and structural durability. Recently,
two-dimensional materials have garnered significant attention as potential platforms for single-photon
emitters, allowing integration with photonic circuits and enabling nanoscale control. However, challenges such
as the spectral diffusion and low quantum yield of quantum emitters are still open questions. In this seminar,
I will present the current status, opportunities, and challenges of single-photon emitters hosted in
two-dimensional materials.
