Advanced Quantum Technologies, Volume 8, Issue 9, September 2025.Hardware experiments show a single‐layer Quantum Memory Matrix booster cuts logical error sixfold and, when prepended to a [3,1,3]$[3,1,3]$ repetition code, attains 94 % logical fidelity without extra CX gates. QMM dressing also lowers variational‐training loss by 35 %, offering a measurement‐free, resource‐light route to error suppression on NISQ ...

Cost‐Effective DNA Storage System with DNA Movable Type
Advanced Science, Volume 12, Issue 9, March 6, 2025.This study presents a cost‐effective “DNA‐movable‐type storage” system inspired by movable type printing. Utilizing reusable prefabricated DNA‐MTs and an automated inkjet printer, BISHENG‐1 stores and retrieves 43.7 KB of data in vitro and in vivo with only 350 DNA‐MTs, achieving storage costs of $122 MB−1–significantly more cost‐efficient than ...

Electronics Letters, Volume 61, Issue 1, January/December 2025.Here, a multi‐user signal iterative detection and decoding scheme named LBEP based on block expectation propagation (BEP) is proposed for LDPC‐coded two‐phase unsourced random access (URA) scheme. In the iteratively process, the approximation of matrix inversion is used to facilitate expectation propagation (EP). The numerical results show that, in the

Protograph EXIT Analysis over Block Fading Channels with Application to Relays
, 2012 An accurate extrinsic information transfer (EXIT) analysis is developed for protograph low-density parity-check (LDPC) codes over the block fading channel (BFC). The analysis is thus exploited for analyzing the behavior of distributed protograph LDPC
