Subsystem Codes with High Thresholds by Gauge Fixing and Reduced Qubit Overhead

We introduce a technique that uses gauge fixing to significantly improve the quantum-error-correcting performance of subsystem codes. By changing the order in which check operators are measured, valuable additional information can be gained, and we introduce a new method for decoding which uses this...
