Open Quantum Dynamics and Spontaneous Symmetry Breaking

Explore a comprehensive physics lecture that delves into the fundamental differences between open and closed quantum systems, focusing on information creation and destruction dynamics. Learn how strong-to-weak spontaneous symmetry breaking (SSB) serves as a unifying framework for understanding information-theoretic phase transitions in quantum systems. Examine the application of this framework to various phenomena, including purification dynamics, charge-sharpening dynamics, quantum error correction, and fault-tolerance thresholds. Delivered by Jong Yeon Lee, a distinguished physicist from the University of Illinois who brings extensive experience from Caltech, Harvard, and the Kavli Institute for Theoretical Physics, this 52-minute presentation bridges the gap between condensed matter physics and quantum information science, offering valuable insights into the complex world of open quantum dynamics.
