Decodable quantum LDPC codes beyond the √n distance barrier using high dimensional expanders [PDF]
Constructing quantum LDPC codes with a minimum distance that grows faster than a square root of the length has been a major challenge of the field. With this challenge in mind, we investigate constructions that come from high-dimensional expanders, in ...

The design of structured LDPC codes with algorithmic graph construction [PDF]
Low-Density Parity-Check (LDPC) codes are among the most effective modern error-correcting codes due to their excellent correction performance and highly parallel decoding scheme.

Rate‐compatible spatially coupled LDPC code ensembles by partial repetition extension
Abstract Herein, one partial repetition extension method is proposed to construct the rate‐compatible spatially coupled low‐density parity‐check (RC‐SCLDPC) codes. For each position of the base SCLDPC code, a certain proportion of the variable nodes are first selected randomly and then repeated a certain number of times.

Connectivity constrains quantum codes [PDF]
Quantum low-density parity-check (LDPC) codes are an important class of quantum error correcting codes. In such codes, each qubit only affects a constant number of syndrome bits, and each syndrome bit only relies on some constant number of qubits ...

Trapping Sets of Quantum LDPC Codes [PDF]
Iterative decoders for finite length quantum low-density parity-check (QLDPC) codes are attractive because their hardware complexity scales only linearly with the number of physical qubits.

Nonbinary Hybrid LDPC Codes [PDF]
In this paper, a new class of low-density parity-check (LDPC) codes, named hybrid LDPC codes, is introduced. Hybrid LDPC codes are characterized by an irregular connectivity profile and heterogeneous orders of the symbols in the codeword. It is shown in particular that the class of hybrid LDPC codes can be asymptotically characterized and optimized ...

Optimizing quasi-cyclic spatially coupled LDPC codes by eliminating harmful objects
It is well known that some harmful objects in the Tanner graph of low-density parity-check (LDPC) codes have a negative impact on their error correction performance under iterative message-passing decoding.
