This course gives an introduction to quantum information theory, targeted to advanced undergraduates and graduate students that have taken a graduate quantum mechanics class on the level of Physics 230. We use symmetries as a guiding principle as well as as a toolbox to study the fundamental features of quantum mechanics and their exploitation for information processing tasks.
