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.

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

Efficient LDPC Encoder Design for IoT-Type Devices

Applied Sciences, 2022
Low-density parity-check (LDPC) codes are known to be one of the best error-correction coding (ECC) schemes in terms of correction performance. They have been utilized in many advanced data communication standards for which the codecs are typically ...

Fast bootstrap and reliable readout using hidden references for DNA data storage

iMeta, Volume 5, Issue 1, February 2026.
This study provides a bootstrap readout framework for DNA data storage based on multiple‐fold hidden references. We employ a multi‐stage alignment and error correction strategy, transforming the de novo readout into a resequencing‐like workflow. Correlation to the hidden watermark reference identifies low‐error‐rate reads, and bit‐wise consensus ...

Spatially Coupled Generalized Low-Density Parity-Check Codes Over Class-A Impulsive Noise Channels

IEEE Access, 2019
In this paper, a class of spatially coupled generalized low-density parity-check (SC-GLDPC) codes with minimum coupling width is introduced to mitigate the Class-A impulsive noise. Codes with minimum coupling width are beneficial to simple code structure,

Secret Key Extraction Using Stable Channel Impulse Response in OFDM Wireless Networks

IET Communications, Volume 20, Issue 1, January/December 2026.
The process of converting a complex impulse response (CIR) highest peak into a binary sequence is called ‘quantisation’. By quantising the CIR highest peaks, Alice and Bob will generate the secret key bit sequences KA and KB, respectively. The number of CIR highest peaks is infinite, and these highest peaks can be easily selected from the set of CIRs ...

Distributed QC-LDPC Coded Spatial Modulation for Half-Duplex Wireless Communications [PDF]

Radioengineering, 2022
The bit error rate (BER) performance of spatial modulation (SM) can be further improved by applying quasi-cyclic low-density parity-check (QC-LDPC) codes recommended in 5G to SM.

Joint Blind Identification of Cyclic Codes and Synchronization Scramblers From Synchronous Scrambling Sequences of Cyclic Codes Based on Soft Decision Information

IET Communications, Volume 20, Issue 1, January/December 2026.
A communication model for collaborative and non‐collaborative scenarios is proposed, where the error correction code used by the transmitter is a cyclic code and the scrambler used is a synchronous scrambler. The contents of the dashed boxes are the tasks of the non‐collaborative receiver and our research targets the contents of the red boxes, that is,

On the Design and Implementation and Evaluation of Euclidean Geometry Quasi-Cyclic LDPC Codes for NAND Flash Memories

IEEE Open Journal of the Communications Society
As data storage demands continue to grow, ensuring the reliability of NAND flash devices after a large number of Program/Erase (P/E) cycles have elapsed has become a critical requirement.
