Fig. 4: Logical error scaling below threshold.

a pL vs p at a fixed code distance d = 5 for various values of Re [colors correspond to the diamond points in panel (c)]. In panel (b), the physical and logical error rates are rescaled by their values at the threshold. c Logical error exponent ν, extracted from the slope of the curves in (b). The dashed lines show the expected asymptotic exponents for pure computational errors (νp = 3) and pure erasure errors (νe = 5). The error bars indicate the 95% confidence interval in the exponent ν, estimated from a chi-squared analysis of the fit.
