Opening up Quantum Criticality

Explore quantum criticality in this hour-long seminar presented by Tim Hsieh from Perimeter Institute. Delve into topics such as long-range entangled matter, mixed states, and open quantum systems. Gain insights into local adaptive circuits, critical mixed states, and local quantum channels. Examine the concept of boundary entropy and learn about the process of criticalizing ground states. This talk, part of the "2022-2023 Quantum Information Seminar" series, offers a comprehensive look at opening up quantum criticality and its implications in quantum information theory.
