Fig. 3: Real-time decoder-based error correction and logical measurement.
From: Real-time processing of stabilizer measurements in a bit-flip code
a Gate sequence with active correction, based on N rounds of stabilized measurements, followed by simultaneous data qubit measurements and majority function. The sequence in each cycle is identical to the uncorrected case in Fig. 2 (including the cavity depletion, not shown). The shaded areas highlight the real-time processing. b Average results d1, d2, d3 following the conditional \(\hat{X}\) gates in a (solid symbols), compared to the uncorrected case (same as Fig. 2b; empty). Dash-dotted (dashed) curves are obtained from numerical simulation for the real-time corrected (uncorrected) case. c Average majority vote m for the data in b. Error bars: range over five repetitions of the experiment (3000 shots each).
