distance of a classical or quantum CSS code

+
+

The program implements two methods:

    +
  1. Random information set (random window) algorithm (upper bound).
    + This works with any code (LDPC or not). (2) depth-first codeword enumeration (connected cluster) algorithm (Lower bound or actual distance if a codeword is found.)
    +
    2. +

distance of a classical or quantum CSS code

The program implements two methods:

    +
  1. Random information set (random window) algorithm (upper bound).
    + This works with any code (LDPC or not). (2) depth-first codeword enumeration (connected cluster) algorithm (Lower bound or actual distance if a codeword is found.)
