Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length

, 2017
In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...

Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network

Advanced Quantum Technologies, Volume 8, Issue 10, October 2025.
The article explores securing a dynamic global quantum network using continuous variable QKD, proposing a unified three‐layer network architecture for integrating existing QKD networks. It evaluates secret key rates across various channels and introduces the link capacity as a metric for determining the optimum path for secret key distribution in a ...

QMM‐Enhanced Error Correction: Demonstrating Reversible Imprinting and Retrieval for Robust Quantum Computation

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 ...

LDPC convolutional codes based on braided convolutional codes [PDF]

2008 IEEE International Symposium on Information Theory, 2008
We introduce and analyze new constructions of LDPC convolutional codes and their tail-biting versions which are obtained from braided convolutional codes. The basic ideas behind the encoding and decoding architectures for these codes are presented. Additionally, asymptotic results concerning the iterative thresholds are shown for different ensembles ...
