EA QC-QLDPC code[1]

Description

One of several EA QLDPC code families constructed from classical QC-LDPC codes with girth at least six. The entanglement assistance removes the dual-containing constraint in the CSS construction, avoiding many 4-cycles while retaining SPA decoding [1].

Decoding

Sum-product algorithm (SPA) decoder [2].
