Description

Recent studies suggest that the symmetries underlying fundamental interactions may have a quantum-information–theoretic origin.By analyzing the relativistic S-matrix as a quantum logic gate acting on the bipartite Hilbert space, one can explicitly trace how Lagrangian-level symmetries are realized in the space of quantum states. In this work, we focus on the entanglement structure in the helicity space, in 2-2 scattering, and demonstrate how distinct symmetry patterns are encoded in the entanglement properties of the scattering states, providing deeper insights and connection between quantum-information and particle scatterings.
