The aims of this course are to review the fundamental principles and methods of information theory. Since Shannon’s landmark work in 1948, information theory has been at the core of information processing systems. Nowadays, information theory finds wide applications in
areas such as communications engineering, probability theory, statistics, physics, computer science, mathematics, economics, bioinformatics and computational neuroscience. The course will cover source coding, rate distortion, data transmission, and multiple-user information theory. The course will not only review the main results of information theory, but will also describe proof methodologies and illustrate the key tradeoffs between the underlying system
parameters. In the last third or quarter of the course, quantum information theory will be discussed, which is the generalization of information theory to systems that are described by quantum mechanics, exhibiting a large range of new phenomena, while giving rise to a theory that has at least partially strong similarity to “classical” information theory. No prior knowledge of quantum physics is required.
