Light-matter interaction at the single-photon level
Many crucial developments in photonic quantum technologies rely on producing, manipulating, and detecting single photons, that can carry quantum information over long distances. In this presentation, I will discuss how solid-state artificial atoms can be realized, based on semiconductor quantum dots in optimized microcavities, and can be used to taylor the light-matter interaction at the single photon level. I will show how the same basic building blocks can be used as optimal emitters of quantum light, but also as optimal receivers, where incoming photons become entangled with the spin state of a single charge, trapped in the artificial atom. I will discuss some short-term and long-term perspectives of this research, in terms of fundamental physics and industrial valorization.
