Advances in fabrication and spectromicroscopy techniques have enabled unprecedented access to quantum mechanical effects underlying various nanophotonic phenomena, challenging their description solely within classical electrodynamics. Here, I will present a suite of quantum-informed theoretical frameworks for accurately describing light– matter interactions in nanophotonics and discuss how these approaches provide new insights and unlock new capabilities. Topics will include quantum corrections to plasmon spectra and plasmon-enhanced light–matter interactions, as well as the exploration of quantum effects governing electron–light–matter interactions in various electron-beam-based spectroscopies of current interest.
