Symmetry Breaking as Quantum Gate: Entropy and Weak Mixing Angle

We establish a correspondence between two independent entropic probes – the variation of Rényi mutual information (RMI) across the electroweak symmetry breaking (EWSB) transition and the stabilizer Rényi entropy (SRE) – in tree-level $2\to 2$ elastic scatterings. After angular averaging, the RMI (helicity basis) and the SRE (fixed beam basis) exhibit identical dependence on ${\sin }^2{\theta }_W$ within each neutral-current channel. We trace this correspondence to a common physical origin that it’s the Yukawa mass insertion acts as a $-\mathrm{i}Y$ quantum gate in chirality space. Minimizing entropies across all processes yields ${\sin }^2{\theta }_W$ values matching purely axial vector-like couplings in $Z$ boson exchanged channel.
