Analyzing the Quantum Effects in Light-Matter Interaction at the Nanoscale

Abstract

Quantum effects dominate the interaction between light and matter at the nanoscale, giving rise to phenomena such as quantum confinement, strong coupling, and photon entanglement. These effects are pivotal in advancing nano-optics, quantum information technologies, and biosensing applications. This paper explores the underlying principles governing quantum light-matter interactions in nanostructures like quantum dots, plasmonic systems, and 2D materials. Emphasis is placed on quantum coherence, spontaneous emission control, and energy quantization. By examining theoretical models and recent experimental advances, we highlight the transformative role of quantum mechanics in nanophotonics and propose future research directions.
