This lecture covers the principles of quantum interference, focusing on fractional statistics including abelian and non-abelian statistics, as well as anyonic statistics. The ultimate proof of exchange statistics is discussed along with interference experiments such as Mach-Zehnder and Fabry-Perot interferometers. The lecture also delves into the concept of anyonic statistics where the phase is a combination of AB and statistical phases, with references to relevant studies and recent observations.
