Prof. Brian Swingle: Information Scrambling in Complex Quantum Systems
20 May 2021 @ 5:30 PM – 6:30 PM IDT
I will describe recent progress in the study of information scrambling driven by new experimental possibilities and by a remarkable convergence of ideas in many-body physics, information, and gravity. The focus will be on the quantum butterfly effect and its relation to the spreading of entanglement and to emergent speed limits. I will also describe how this physics is being probed in the lab, focusing on recent results from programmable quantum devices and on nuclear magnetic resonance experiments.
