Fig. 2: Real-time repeated error correction with ancilla reset.

a Gate sequence for independent cycles of active error correction. b Average digitized result for each of D1 (red), D2 (blue), and D3 (green) measurements after initialization in \(\left|111\right\rangle\) and N cycles of a (full symbols). The results are compared to those obtained with the same circuit, but where data correct and ancilla reset operations are omitted (empty symbols). c Average majority vote m for the data in b. The closed-loop circuit (full symbols) does not improve over open loop (empty). In both b and c, solid (dashed) curves are obtained from numerical simulation for the corrected (uncorrected) case (Supplementary Methods). Error bars: range over five repetitions of the experiment (3000 shots each).
