Generalized quantum data-syndrome codes and belief propagation decoding for phenomenological noise [PDF]

arXiv, 2023
Quantum stabilizer codes often struggle with syndrome errors due to measurement imperfections. Typically, multiple rounds of syndrome extraction are employed to ensure reliable error information. In this paper, we consider phenomenological decoding problems, where data qubit errors may occur between extractions, and each measurement can be faulty.

Post-cholecystectomy syndrome: A new look at an old problem

Journal of Minimal Access Surgery, 2018
Background: Despite being the most commonly performed operations, sometimes cholecystectomy fails to relieve symptoms; this is now a well-recognised clinical entity termed 'post-cholecystectomy syndrome' (PCS).

Is A Quantum Stabilizer Code Degenerate or Nondegenerate for Pauli Channel? [PDF]

arXiv, 2010
Mapping an error syndrome to the error operator is the core of quantum decoding network and is also the key step of recovery. The definitions of the bit-flip error syndrome matrix and the phase-flip error syndrome matrix were presented, and then the error syndromes of quantum errors were expressed in terms of the columns of the bit-flip error syndrome ...

Syndrome-aware Herb Recommendation with Multi-Graph Convolution Network [PDF]

arXiv, 2020
Herb recommendation plays a crucial role in the therapeutic process of Traditional Chinese Medicine(TCM), which aims to recommend a set of herbs to treat the symptoms of a patient. While several machine learning methods have been developed for herb recommendation, they are limited in modeling only the interactions between herbs and symptoms, and ...

Syndrome Measurement Order for the [[7,1,3]] Quantum Error Correction Code [PDF]

arXiv, 2013
In this work we explore the accuracy of quantum error correction depending of the order of the implemented syndrome measurements. CSS codes require bit-flip and phase flip-syndromes be measured separately. To comply with fault tolerant demands and to maximize accuracy this set of syndrome measurements should be repeated allowing for flexibility in the ...

Utility of endoscopic ultrasound to diagnose remnant stones in symptomatic patients after cholecystectomy [PDF]

, 2014
Background and study aims: Stones in the cystic duct stump (CDS) or gallbladder remnant after cholecystectomy are difficult to identify. The aim of this study was to evaluate the utility of endoscopic ultrasound (EUS) in the diagnosis of stones in the ...

Correction of Data and Syndrome Errors by Stabilizer Codes [PDF]

arXiv, 2016
Performing active quantum error correction to protect fragile quantum states highly depends on the correctness of error information--error syndromes. To obtain reliable error syndromes using imperfect physical circuits, we propose the idea of quantum data-syndrome (DS) codes that are capable of correcting both data qubits and syndrome bits errors.

Management of chronic postsurgical pain following cholecystectomy

Indian Journal of Pain, 2018
A 50-year-old female presented with severe pain at the cholecystectomy scar site of 4 months' duration. She had an open cholecystectomy done followed by continuous pain from the time of discharge. She was diagnosed as a case of chronic postsurgical pain (

Learning from the Syndrome [PDF]

arXiv, 2018
In this paper, we introduce the syndrome loss, an alternative loss function for neural error-correcting decoders based on a relaxation of the syndrome. The syndrome loss penalizes the decoder for producing outputs that do not correspond to valid codewords.

Ternary Syndrome Decoding with Large Weight [PDF]

arXiv, 2019
The Syndrome Decoding problem is at the core of many code-based cryptosystems. In this paper, we study ternary Syndrome Decoding in large weight. This problem has been introduced in the Wave signature scheme but has never been thoroughly studied. We perform an algorithmic study of this problem which results in an update of the Wave parameters.
