Operator algebras seminar
Christian Voigt (University of Glasgow)
Quantum graphs are certain noncommutative objects which generalize (finite) classical graphs. They have featured recently in connection with the graph isomorphism game in quantum information. In this talk I’ll review some of this background and then present a definition of “quantum graph C*-algebras”, in analogy to (and generalizing) the well-known C*-algebras associated with directed graphs.
