After successful completion of the course, students are able to solve simple quantum optical problems, to analyse coherence effects, to define the complementarity in light theory, to explain interference of photons using beam splitters and Mach-Zehnder interferometers, to describe entanglement using bosonic algebra as well as to derive derive Feynmans path integral method.

Basics for quantum optics and interferometry, theory of quantum mechanical distribution functions, Wigner function, Q - Function, P-function, squeezed states, optical interferometry. Interference of single photons and of coherent beams, quantum-mechanical description of the beam splitter, two photons and beam splitter (Hong-Ou-Mandel-Effect), Mach-Zehnder interferometer, coherence functions, entanglement, complementarity.

A well-written manuscript (110 pages) is used and presented using a beamer. Discussions during the lessons are wellcome.
