Decoder for hybrid color-toric codes

Implementation of the decoding algorithm for two-dimensional hybrid color-toric codes described in arXiv:2112.01446

Build

• mkdir build && cd build
• cmake ../ -DCMAKE_BUILD_TYPE=Release
• make

Usage

• Use gen_input.py in input to generate a parameter file
  • L is linear lattice length for an LxL torus (must be a multiple of three)
  • eP is phase-flip error probability
  • uP is the morphing (unencoding) probability
  • disorder is the number of lattices to generate for each uP
• Use monte_carlo.py to run experiments using a parameter file
• Also included example script for running on a cluster (array-job.sh)

Notes

To only morph red ball-like regions, set rOnly to true in main.cpp

Tests

• cd build
• cmake ../ -DCMAKE_BUILD_TYPE=Debug
• make
• make test

Software

This code makes use of Blossom V and Boost
