On the Stopping Distance of SA-LDPC Codes by Transversal Designs

IEEE Access, 2018
In this paper, we analyze the size of the smallest stopping set (called the stopping distance) for the parity-check matrix of a superposed array low-density parity-check (SA-LDPC) code for column weights 3 and 4 by using the transversal design (TD ...

A Resource Efficient Ising Model‐Based Quantum Sudoku Solver

Software: Practice and Experience, Volume 56, Issue 6, Page 643-657, June 2026.
ABSTRACT Background Quantum algorithms exploit superposition and parallelism to address complex combinatorial problems, many of which fall into the non‐polynomial (NP) class. Sudoku, a widely known logic‐based puzzle, is proven to be NP‐complete and thus presents a suitable testbed for exploring quantum optimization approaches.

Implementation of Decoders for LDPC Block Codes and LDPC Convolutional Codes Based on GPUs [PDF]

IEEE Transactions on Parallel and Distributed Systems, 2014
With the use of belief propagation (BP) decoding algorithm, low-density parity-check (LDPC) codes can achieve near-Shannon limit performance. In order to evaluate the error performance of LDPC codes, simulators running on CPUs are commonly used. However, the time taken to evaluate LDPC codes with very good error performance is excessive. In this paper,

From Product Codes to Structured Generalized LDPC Codes

, 2010
Product codes, due to their relatively large minimum distance, are often seen as a natural solution for applications requiring low error floors.

Radiation‐Induced Fault Detection in Superconducting Quantum Devices

Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.
Cosmic rays cause correlated errors in superconducting quantum computers. Quantum error correction codes are not sufficient to solve this issue, as such a real‐time logical detector for radiation faults has been developed. It identifies radiation faults with high accuracy, providing information which could be used to revert the effects of radiation and

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, Volume 200, Issue 3, Page 661-672, March 2026.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]

, 2013
Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.
