Fig. 3: Circuit-level error thresholds in the presence of erasure errors.

a Scaling of the logical error rate with the physical qubit error rate p in the case of pure computational errors (R_e = 0, open circles, dashed lines) and in the case of a high conversion to erasure errors, R_e = 0.98 (filled circles, solid lines). The error thresholds are p_th = 0.937(4)% and p_th = 4.15(2)%, respectively, determined from the crossing of d = 11 and d = 15. The error bars indicate the 95% confidence interval in p_L, estimated from the number of trials in the Monte Carlo simulation. b p_th as a function of R_e (The green star highlights R_e = 0.98).
