Applications of Generalized Symmetry in Quantum Computation

Explore a 38-minute conference talk by Po Shen Hsin from King's College London on the applications of generalized symmetry in quantum computation, recorded during the "Generalized Symmetries: High-Energy, Condensed Matter and Mathematics" conference at the Kavli Institute for Theoretical Physics (KITP) at UC Santa Barbara. Discover how the past decade has seen remarkable progress in quantum field theory through understanding symmetries as topological defects acting on operator spaces. Learn about this generalized concept of symmetries and its implementation through Lagrangian field theory techniques, revealing unexpected physical effects across condensed matter, high energy physics, and quantum gravity. This presentation is part of a conference bringing together leading experts to share recent advances and open problems in the field, coordinated by Maissam Barkeshli, Michele Del Zotto, Sakura Schafer-Nameki, and Shu-Heng Shao.
