The non-Abelian W.-Z. phase factor is numerically evaluated by solving the time-dependent Schrödinger equation for our experimental condition for the path \({{{{\mathcal{C}}}}}_{-}\) with θ2 = π/4 and analyzed by following the same procedure used in the experiment to numerically obtain the process matrix. The solid line is a power-law fit to the numerical results.
