Optimization of LDGM-based quantum codes using Density Evolution

Publisher

Abstract

We introduce the use of Discrete Density Evolution (DDE) to optimize LDGM-based quantum codes. These are Calderbank-Shor-Steane (CSS) codes based on the generator and parity-check matrices of an LDGM code, which is designed with a specific structure inspired in the parallel concatenation of LDGM codes. The proposed codes allow greater flexibility and are easier to design than existing sparse-graph CSS quantum codes, while leading to better performance.

Asymptotic analysis of LDGM-based quantum codes

Kejing Liu, Javier Garcia‐Frias

We study the error floor performance of a proposed family of LDGM-based quantum codes. LDGM-based quantum codes are Calderbank-Shor-Steane (CSS) codes based on the generator and parity-check matrices of a classical LDGM code. Decoding is performed in an iterative manner, by applying message passing over the corresponding graphs. The proposed codes allow greater flexibility and are easier to design than existing sparse-graph CSS quantum codes, while leading to better performance.

LDGM-Based Quantum Codes for Fault-Tolerant Quantum Computation

Yumin Li, Kejing Liu, Hanqing Lou +1 more

We construct a new family of Calderbank-Shor-Steane (CSS) codes using the generator and parity-check matrices of Low-Density Generator Matrix (LDGM) codes, with row operations applied to both matrices in order to achieve the desired quantum rate. Decoding is performed in an iterative manner, by applying message passing over the associated graph, and discrete Density Evolution (DDE) is used to optimize performance in the depolarizing channel. The proposed construction offers high flexibility and easiness in the design, producing quantum codes that possess excellent error correction capabilities. By properly designing the structure of the code, we are able to control and bound the weight of the stabilizer generators to a small value, which results in codes particularly well suited for fault-tolerant quantum computation. At the same time, these codes achieve very good performance in terms of error correction capability.

Design of near-optimum quantum error-correcting codes based on generator and parity-check matrices of LDGM codes

Javier Garcia‐Frias, Kejing Liu

We study the design of near-optimum quantum error correcting codes based on the use of sparse matrices. The basic idea is to construct a Calderbank-Shor-Steane (CSS) code based on the generator and parity-check matrices of a classical channel code with low density generator matrix (LDGM code), which is designed with a specific structure inspired in the parallel concatenation of regular LDGM codes. Then, row operations are performed in both matrices to achieve the desired quantum rate. Decoding is performed in an iterative manner, by applying message passing over the corresponding graphs. The proposed codes allow greater flexibility and are easier to design than existing sparse-graph quantum codes, while leading to better performance.

Approach for the construction of non-Calderbank-Steane-Shor low-density-generator-matrix–based quantum codes

Patricio Fuentes, Josu Etxezarreta Martínez, Pedro M. Crespo +1 more

Quantum low-density generator matrix (QLDGM) codes based on Calderbank-Steane-Shor (CSS) constructions have shown unprecedented error correction capabilities, displaying much improved performance in comparison to other sparse-graph codes. However, the nature of CSS designs and the manner in which they must be decoded limit the performance that is attainable with codes that are based on this construction. This motivates the search for quantum code design strategies capable of avoiding the drawbacks associated with CSS codes. In this article, we introduce non-CSS quantum code constructions based on classical LDGM codes. The proposed codes are derived from CSS QLDGM designs by performing specific row operations on their quantum parity check matrices to modify the associated decoding graphs. The application of this method results in performance improvements in comparison to CSS QLDGM codes, while also allowing for greater flexibility in the design process. The proposed non-CSS QLDGM scheme outperforms the best quantum low-density parity check codes that have appeared in the literature.

Quantum CSS LDPC Codes based on Dyadic Matrices for Belief Propagation-based Decoding

Alessio Baldelli, Massimo Battaglioni, Jonathan Mandelbaum +2 more

Quantum low-density parity-check (QLDPC) codes provide a practical balance between error-correction capability and implementation complexity in quantum error correction (QEC). In this paper, we propose an algebraic construction based on dyadic matrices for designing both classical and quantum LDPC codes. The method first generates classical binary quasi-dyadic LDPC codes whose Tanner graphs have girth 6. It is then extended to the Calderbank-Shor-Steane (CSS) framework, where the two component parity-check matrices are built to satisfy the compatibility condition required by the recently introduced CAMEL-ensemble quaternary belief propagation decoder. This compatibility condition ensures that all unavoidable cycles of length 4 are assembled in a single variable node, allowing the mitigation of their detrimental effects by decimating that variable node.

Decoding is performed in an iterative manner, using message passing over the corresponding graphs.
