a \(\Delta | {\rho }_{23}^{{{{\rm{n}}}}}{| }^{2}\) as a function of ϕ with the initial state \(\left\vert {u}_{z}(\phi )\right\rangle\) at Ω/γ = 2. b \(\Delta | {\rho }_{13}^{{{{\rm{n}}}}}{| }^{2}\) as a function of ϕ with the initial state \(\left\vert {u}_{x}(\phi )\right\rangle\) at Ω/γ = 0.5. The zero points are marked by circles and crosses, determined by linear interpolation between adjacent experimental data points with opposite signs, and error bars denote the standard deviation.
