# Math Physics Seminar

Speaker:

David Kribs, Institute for Quantum Computing

Topic:

Operator theory and distinguishing quantum states with LOCC

**Abstract:**

In this talk, I'll discuss work with collaborators on a fundamental problem in quantum information: Given a known set of quantum states, when can two parties distinguish the states under the restricted and hybrid classical-quantum communication setting called local (quantum) operations and classical communication (LOCC). I'll show how we've been able to make use of some tools from operator theory and operator algebras to solve certain subproblems, and more recently how graph theory has also played a role in our work. This talk is based on joint works with Comfort Mintah, Michael Nathanson, and Rajesh Pereira.
