Short description of the course:

Broadly speaking, quantum information theory is a set of mathematical tools that aims to quantify the amount of information and/or correlation present in random variables or quantum systems, and that applies these tools to problems such as data compression and coding over noisy channels. While information theory has traditionally been focused on problems of an asymptotic nature (i.e. n copies of the same channel, with n → ∞), so-called "one-shot" information theory considers finite-size problems. In addition to being more general, this point of view is also much more suitable for cryptographic applications (since malicious adversaries can rarely be assumed to have an "asymptotic" behavior), and in particular is indispensable for e.g. proving the security of quantum key distribution. This series of lectures will introduce this one-shot theory of quantum information and present some of its applications.
