Goal(s)

These lectures are aimed to provide building blocks to understand and model the elementary components of light (photons), light matter-interaction at the single photon level, and elements of quantum communication and information processing with single photons. It will be illustrated by examples from Atomic Physics and Solid State Physics (superconducting quantum circuits, semiconductor nanostructures).
