Quantum Optical Communication
MIT's graduate course 6.453 covers the physics and engineering of quantum information carried on light. Lectures build from single-mode and two-mode quantum optical systems up through multi-mode fields, covering quantum descriptions of coherent states, squeezed light, and photon detection statistics. The course treats nonlinear optics as a tool for generating quantum light sources and works through quantum system theory as applied to optical communication channels, including capacity limits set by quantum mechanics. Materials on MIT OpenCourseWare include lecture notes, problem sets, and readings drawn from the quantum optics and quantum information literature. No video lectures are included, but the written materials are complete enough to follow the course topic by topic. Intended for students with a background in electromagnetics and quantum mechanics, it sits at the advanced end of MIT's electrical engineering curriculum. Free to access, with no certificate offered.
