Quantum Communication Theory
7:30 pm, March 9, Buchanan A100

Charles H. Bennett

IBM -- Yorktown Heights

When classical notions of information are generalized to obey the superposition principle of quantum physics, a simpler and grander theory of communication and computation emerges, extending the old theory somewhat as the complex numbers extend the real. Within this larger theory, classical information plays its usual robust role, while quantum information, in its fragility and privacy, may be compared to the information in a dream. We sketch the outlines of the enlarged theory, especially the pervasive role of entanglement in a variety of communications tasks that have no direct classical analog.
