Quantum Field Theory

Tobias Osborne is a researcher in quantum information theory based at the Institut fur Theoretische Physik, Leibniz Universitat Hannover. Tobias gives a course on quantum field theory. This course is intended for theorists with familiarity with advanced quantum mechanics and statistical physics. The main objective is to introduce the building blocks of quantum electrodynamics.
