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.
