Cryptographic error correction
… to solve classical problems from the theory of error correction; and second, by studying special kinds of codes that are motivated by cryptographic applications. In the first part of this thesis, we consider a model of error correction in which the source of errors is adversarial, but limited to …

Channel-adapted quantum error correction
Quantum error correction (QEC) is an essential concept for any quantum information processing device. Typically, QEC is designed with minimal assumptions about the noise process; this generic assumption exacts a high cost in efficiency and performance. We examine QEC methods that are adapted to the …

FPGA acceleration of DNA error correction
Correcting errors in DNA sequencing data is an important process that can improve the quality of downstream analyses using the data. Even though many error-correction methods have been proposed for Illumina reads, their throughput is not high enough to process data from large genomes. The thesis …

Error-correction on non-standard communication channels
… time-varying noise, cross-talk, synchronization errors and latency constraints. In this thesis, low-density parity-check codes and codes related to them are applied to non-standard channels. First, we look at time-varying noise modelled by a Markov channel. A low-density parity-check code decoder …

Second order error correction in quantum computing
Error correction codes are necessary for the development of reliable quantum computers. Such codes can prevent the lost of information from decoherence caused by external perturbations. This thesis evaluates a five qubit code for correcting second order bit-flip errors. The code consists of …

Extensible Platforms for Bosonic Quantum Error Correction
Bosonic quantum error correction (QEC) encodes information in the phase space of a quantum harmonic oscillator and offers a hardware-efficient path towards faulttolerant quantum information processing. With superconducting circuits, bosonic QECusing the Gottesman-Kiteav-Preskill (GKP) encoding has …

Natural error correction techniques for sketch recognition
… the sketch once it's been drawn, whether the error is the user's or the sketch recognizer's. In response, we developed and studied intuitive methods of interacting with a sketch recognition system to correct errors made by both the recognizer and the user. The editor allows users to click and …

Device- and application-adapted quantum error correction
… technique to this end is called quantum error correction, which encodes quantum states in such a way that errors can be detected and corrected, much like in classical error-correcting codes. Quantum error-correcting codes usually cast a wide net, in that they are designed to correct …

Error Correction in Next Generation DNA Sequencing Data
… the genome of a species quickly and cheaply. Errors that are introduced by NGS technologies limit the full potential of the applications that rely on their data. Current techniques used to correct these errors are not sufficient, and a more efficient and accurate program is needed to correct …

Trellis Decoding And Applications For Quantum Error Correction
Compact, graphical representations of error-correcting codes called trellises are a crucial tool in classical coding theory, establishing both theoretical properties and performance metrics for practical use. The idea was extended to quantum error-correcting codes by Ollivier and Tillich in 2005. …

A Double-Error Correction Computational Model of Learning
In this thesis, the Double Error model, a general computational model of real-time learning is presented. It builds upon previous real-time error-correction models and assumes that associative connections form not only between stimuli and reinforcers, but between all types of stimuli in a …

Designing methods for error correction in gene fabrication
… DNA target, but to do so without making any errors. At high error rates, fabrication of long gene targets is expensive and impractical - in some cases, it is impossible. Improvements in error rates are essential for continued progress in the development of gene fabrication technology. Error …

Synthesis and error correction methods in gene fabrication
… The second part of this document focuses on error correction. Reducing error rates is one of the main challenges in gene fabrication because high error rates preclude the possibility of fabricating long gene targets in a practical and economical manner. Improvements in error rates are …

Automatic annotation of error types for grammatical error correction
Grammatical Error Correction (GEC) is the task of automatically detecting and correcting grammatical errors in text. Although previous work has focused on developing systems that target specific error types, the current state of the art uses machine translation to correct all error types …
