Description
Recent work has highlighted a surprising connection between quantum information and high energy physics.In this talk, I will discuss how symmetry and general consistency conditions constrain the entanglement structure of scattering amplitudes, largely independent of detailed dynamics.In Yang–Mills theory, symmetry alone strongly constrains this structure, leading to universal entanglement features independent of detailed dynamics. I will also show how these features can be used to probe effective field theory deformations, and how simple entanglement-based constraints can uniquely select Yang–Mills theory within a broad class of interactions. These results suggest a new, information-theoretic perspective on the structure of quantum field theories.
