Duke Physics Colloquium: Quantum Entanglement for Fun and Profit: 101 Uses for Schroedinger's Cat

Nearly 80 years after Schroedinger described entanglement as the quintessential nonclassical phenomenon, and 50 years after Bell showed the inconsistency of quantum correlations with local realism, the quantum information revolution seeks to use its almost magical properties to enable new feats in information processing. As we shall see, entanglement can now be produced at high rates with exquisite precision, enabling unprecedented tests of nonlocality and 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). Time and appetites permitting, I may give a brief lesson in quantum cooking. Faculty Host: Daniel Gauthier. Refreshments will be served before and after the event in room 128.
