John Watrous (University of Calgary): Theory and Potential Applications of Quantum Information Processing

Several discoveries suggesting that quantum mechanics offers powerful tools for performing various information processing tasks have been made in recent years. Examples include quantum cryptography, which allows unconditionally secure key exchange, and algorithms for quantum computers that outperform all known classical algorithms for certain problems. Unfortunately, physically implementing these schemes promises to be a enormous technological challenge with nothing even approaching a guarantee of success. In this talk I will discuss some of the theoretical developments and (realistic) potential applications of this field.
