Please join the Photonics Initiative for a one-hour seminar from Aashish Clerk, University of Chicago, titled:
Non-reciprocal quantum interactions from gauge symmetry
Abstract – The most common kinds of interactions in physics obey a basic kind of reciprocity: when two systems or particles interact, each one influences the other, and information flows in both directions. Engineering quantum interactions that break this symmetry is of both fundamental and practical interest. In this talk, I will describe a new approach for realizing one-way quantum interactions that does not require breaking time-reversal symmetry, but instead makes use of a local gauge symmetry present in any Markovian dissipative quantum dynamics. This new route to quantum non-reciprocity is compatible with many experimental setups, and enables a new, dissipatively-stabilized approach for implementing quantum gates. I will also discuss a new, extremely general quantum information-baed metric that allows one to rigorously quantify and compare different kinds of quantum non-reciprocal interactions.
Bio – Aashish Clerk is a theoretical physicist and Professor of Molecular Engineering at the University of Chicago. Clerk’s research focuses on understanding complex phenomena in quantum systems that are both strongly driven and subject to dissipation; it intersects the fields of condensed matter, quantum optics and quantum information. His research has applications to various areas of quantum technology, including sensing, control, communication and computing. He received his BSc from the University of Toronto and a PhD in Physics from Cornell University. Prior to joining the Pritzker School of Molecular Engineering, Professor Clerk served as Professor of Physics and Tier-1 Canada Research Chair at McGill University. His work has been recognized by several awards, including a 2020 Simons Foundation Investigator in Physics Fellowship, and the 2015 Rutherford Medal in Physics from the Royal Society of Canada.
This event will be held in the ASRC auditorium, while broadcast via Zoom.
