A Novel Error Correction Mechanism for Energy-Efficient Cyber-Physical Systems in Smart Building

open access: yesIEEE Access, 2018
Smart building is an effective solution to address the issue of energy consumption in today's cyber-physical systems (CPSs) connected world. As an important tool to collect information from a fleet of electric appliance that installed in the building ...

Exact Performance of Concatenated Quantum Codes [PDF]

open access: yes, 2002
When a logical qubit is protected using a quantum error-correcting code, the net effect of coding, decoherence (a physical channel acting on qubits in the codeword) and recovery can be represented exactly by an effective channel acting directly on the ...

Adaptive Syndrome Extraction

open access: yesPRX Quantum
Device error rates on current quantum computers have improved enough to where demonstrations of error correction below break even are now possible. Still, the circuits required for quantum error correction introduce significant overhead and sometimes ...

Concatenated Quantum Codes [PDF]

open access: yes, 1996
One of the main problems for the future of practical quantum computing is to stabilize the computation against unwanted interactions with the environment and imperfections in the applied operations.

Error suppression and error correction in adiabatic quantum computation: non-equilibrium dynamics

open access: yesNew Journal of Physics, 2013
While adiabatic quantum computing (AQC) has some robustness to noise and decoherence, it is widely believed that encoding, error suppression and error correction will be required to scale AQC to large problem sizes.

VLSI single-chip (255,223) Reed-Solomon encoder with interleaver [PDF]

open access: yes, 1990
The invention relates to a concatenated Reed-Solomon/convolutional encoding system consisting of a Reed-Solomon outer code and a convolutional inner code for downlink telemetry in space missions, and more particularly to a Reed-Solomon encoder with ...

Monte Carlo analysis of critical phenomenon of the Ising model on memory stabilizer structures

open access: yes, 2009
We calculate the critical temperature of the Ising model on a set of graphs representing a concatenated three-bit error-correction code. The graphs are derived from the stabilizer formalism used in quantum error correction.

Near-Hashing-Bound Multiple-Rate Quantum Turbo Short-Block Codes

open access: yesIEEE Access, 2019
Quantum stabilizer codes (QSCs) suffer from a low quantum coding rate since they have to recover the quantum bits (qubits) in the face of both bit-flip and phase-flip errors. In this treatise, we conceive a low-complexity concatenated quantum turbo code (

Optimal Linear Codes with a Local-Error-Correction Property

open access: yes, 2012
Motivated by applications to distributed storage, Gopalan \textit{et al} recently introduced the interesting notion of information-symbol locality in a linear code.
