Decoding of Quantum Data-Syndrome Codes via Belief Propagation [PDF]
in Proc. IEEE International Symposium on Information Theory
(ISIT), 2021, pp. 1552--1557, 2021 Quantum error correction is necessary to protect logical quantum states and operations. However, no meaningful data protection can be made when the syndrome extraction is erroneous due to faulty measurement gates. Quantum data-syndrome (DS) codes are designed to protect the data qubits and syndrome bits concurrently.

Syndrome decoding by quantum approximate optimization [PDF]
Quantum Inf Process 23, 368 (2024), 2022 The syndrome decoding problem is known to be NP-complete. The goal of the decoder is to find an error of low weight that corresponds to a given syndrome obtained from a parity-check matrix. We use the quantum approximate optimization algorithm (QAOA) to address the syndrome decoding problem with elegantly-designed reward Hamiltonians based on both ...

Adaptive syndrome measurements for Shor-style error correction [PDF]
Quantum 7, 1075 (2023), 2022 The Shor fault-tolerant error correction (FTEC) scheme uses transversal gates and ancilla qubits prepared in the cat state in syndrome extraction circuits to prevent propagation of errors caused by gate faults. For a stabilizer code of distance $d$ that can correct up to $t=\lfloor(d-1)/2\rfloor$ errors, the traditional Shor scheme handles ancilla ...

Etiological diagnosis, prognostic significance and role of electrophysiological study in patients with Brugada ECG and syncope. [PDF]
, 2017 BACKGROUND: Syncope is considered a risk factor for life-threatening arrhythmias in Brugada patients. Distinguishing a benign syncope from one due to ventricular arrhythmias is often difficult, unless an ECG is recorded during the episode.
