Clifford-deformed elongated compass codes exhibit bias-dependent thresholds and outperform the XZZX surface code at moderate dephasing biases under code capacity noise.
Circuit-level simulations show correlated MWPM decoding improves thresholds of bias-tailored compass codes under biased noise, with greater relative gains for asymmetric stabilizers.
The paper compiles a curated handbook reference of error-correcting codes, their symbol-based classifications, and interrelations with mathematical objects and physical phases.
