Bound (7) on the variance discrepancy, $|\Delta^2\hat{\phi}^{\prime}-\Delta^2\hat{\phi}|$, against $\phi$ ($^\circ$), for the same dephasing channel (bottom panel). Only the red bound is shown; the printed blue discrepancy curve is not.
This panel was computed from the analytic model published in the paper. The plot shown here is re-rendered for interactive viewing and analysis. See the paper for the original figure and full scientific context.
