Quantum Error Correction: A Window to Complex Quantum States and Dynamics

Explore the fascinating intersection of quantum error correction and complex quantum states in this illuminating lecture by Jeongwan Haah from Microsoft Research. Delve into the origins of quantum error correction as a solution to environmental noise in quantum computing, and discover its unexpected connections to gauge theories. Examine how this perspective has influenced quantum fault-tolerant protocols and revolutionized our understanding of many-body physics, particularly in topological phases. Learn about the emergence of topological field theories in 2+1 dimensions, fracton physics in 3+1 dimensions, and the intriguing relationships between Floquet dynamics and codes. Gain valuable insights into this ongoing cross-fertilization between quantum computing and fundamental physics in this comprehensive 1-hour 7-minute talk from the Stanford Physics Applied Physics/Physics Colloquium series.
