Developments in Wave-Particle Duality
CQT Colloquium
Speaker: Mark Hillery, Hunter College
Abstract: Wave-particle duality is one of the fundamental features of quantum mechanics. This was formalized by a number of duality relations that quantified wave and particle behavior and showed that their total cannot exceed a particular limit. Recently, the resource theory of quantum coherence has given us new ways of quantifying wave behavior, and these have been incorporated into new duality relations. These coherence measures have operational meanings. Some of the duality relations can be formulated as games. Finally, it is possible to make measurements that provide partial wave and particle information, and we formulate limitations on how much total information can be extracted by these measurements.
