This course is an introduction to the theory of quantum communication. We will start with a brief overview of quantum information theory. We will then explore the current state of knowledge in quantum and private communication, including one-shot and asymptotic communication capacities. Finally, we will discuss some topics at the frontiers of quantum communications research, such as second-order asymptotic results for secure key rates in quantum key distribution, and the design of quantum repeater networks for a global-scale quantum internet.
