The Quantum Information
Revolution:
101 Uses for
Schroedinger’s Cat
A century after Einstein's
revolutionary suggestion that light is composed of particles, the quantum
information revolution seeks to use the almost magical properties of
nonclassical physics to enable new feats in information processing. The
critical quantum resource is entanglement, which can now be produced at high
rates with exquisite
precision, enabling such feats as quantum cryptography and teleportation.
I will describe some of these "miracles", and our investigations into
how the usual benefits can be further extended, by using more complex quantum
states (e.g., "hyper-entanglement"), and by incorporating other
elements of modern physics (e.g., special relativity). Time and appetites
permitting, I may give a brief lesson in quantum cooking.
