Title: Positive and completely positive maps via free additive powers of probability measures
Time/Date: 4:30-6:00, Wed. June 4, 2014
Abstract: We give examples of maps between matrix algebras with different "degrees" of positivity using ideas from free probability. We discuss applications to entanglement detection in quantum information theory, and compare the new methods with existing ones.
