This repository contains results and python source code to reproduce the results in "Clifford-Deformed Compass Codes" by Julie A. Campos and Kenneth R. Brown. We can design efficient quantum error correcting (QEC) codes by tailoring them to our choice of quantum architecture. Useful tools for constructing such codes include Clifford deformations and appropriate gauge fixings of compass codes. In this work we find Clifford deformations that can be applied to elongated compass codes resulting in QEC codes with improved performance under noise models with errors biased towards dephasing commonly seen in quantum computing architectures. These Clifford deformations enhance decoder performance by introducing symmetries while the stabilizers of compass codes can be selected to obtain more information on high-rate errors. As a result the codes exhibit thresholds that increase with bias and display lower logical error rates. Notably one of the Clifford deformations we explore yields QEC codes with thresholds and logical error rates superior to those of the XZZX surface code at moderate biases.
