## Content

In modern quantum optics experiments, the quantum nature of light and matter can be directly studied. Using atoms and photons, many of the fascinating "Gedanken"experiments of quantum mechanics can now be realized in the laboratory. Novel experimental techniques enable measurements of highest precision and new applications in quantum information. Experiment and theory are often closely connected in this field.

This lecture gives an introduction to quantum optics. We will discuss the basic phenomena and develop the necessary theoretical tools, as well as discuss key experiments in the field. The goal is to provide a solid background for research in quantum optics and related fields.

## Topics

- Quantized harmonic oscillator, Fock states
