Description
We study the quantum entanglement in Yang-Mills theory. Due to the Color-Kinematic duality, the color and helicity parts are separable which enables the study of the quantum entanglement in color space and helicity space individually. In color space, we compute the quantum entanglement in the SU(2) and SU(3) gauge group and display the large N limit. The Dimension-six operators preserve this universality, while dimension-eight deformations populate new color sectors and shift entanglement , suggesting that entanglement in color space functions as a tomographic probe of effective operators. In the helicity space, we show that the final states always remain maximally entangled with the maximally entangled initial state. This is related to the MHV property of the YM scattering amplitude at tree level. Our results suggest that the information-theoretic viewpoint unifies algebraic, geometric, and dynamical aspects of scattering.
