GB-codes

This repository contains the quantum error-correcting codes constructed by Renyu Wang and Leonid P. Pryadko for the paper "Distance bounds for generalized bicycle codes".

Files

• The zip arxive gb-codes.zip contains the actual code files in the MTX format.
• The file gb-verify.gap contains the list of all codes (circulant length, distance, and two lists of degrees of the non-zero monomials) and a GAP program to verify the distance or write the files.
• The file gb-verify_gap.out.gz is the stdout generated by running gap.sh gb-verify.gap.

Parameters of the codes

The following is the output of zgrep dZ= gb-verify_gap.out.gz
