Title: Quantum Privacy and Complementarity

Abstract: The first significant real-world applications of quantum information appear to be around the corner in the realm of cryptography and communication privacy. Private quantum channels and codes are a fundamental notion in quantum privacy, initially discovered almost two decades ago through efforts to construct quantum analogues of the classical one-time pad. In recent years the subject has blossomed, with a new focus on the development of a structure theory for private quantum codes. These recent efforts have partly been motivated by a realization that private quantum codes are complementary, in a mathematically explicit way, to quantum error correcting codes. I will give an introduction to the topic in this talk, with focus on mathematical aspects of the emerging theory and connections with quantum error correction.
