Quantum walks, i.e., quantum evolution of a particle moving on some underlying graph structure, play an important role in quantum information theory. The system is said to be open if it interacts with its environment, i.e., the evolution loses information and is therefore nonreversible. In this sense, open quantum walks can be considered as quantum analogs of Markov chains. We will give an introduction to open quantum walks in the context of operator algebras and look at some examples coming from Cayley graphs of monoids.
ASUERAU C*-Seminar
August 24, 2022
WXLR A307 and virtual via Zoom
1:30-2:45pm MST/AZ
Our C*-Seminar will again be on Wednesdays from 1:30-2:45 pm (Arizona time, no daylight savings), meeting both in person (WXLR A307) and via zoom.
Also new: it's now the ASUERAU C*-Seminar (so, joint with our friends Lara and Mitch at Embry-Riddle Aeronautical University up the road in Prescott).
(Please email the organizer John Quigg quigg@asu.edu to be put on the email list if you would like to receive the link to the zoom seminar.)
