Testing a quantum error-correcting code on various platforms

open access: yes, 2021
Quantum error correction plays an important role in fault-tolerant quantum information processing. It is usually difficult to experimentally realize quantum error correction, as it requires multiple qubits and quantum gates with high fidelity.

Realization of an Error-Correcting Surface Code with Superconducting Qubits

open access: yes, 2022
Quantum error correction is a critical technique for transitioning from noisy intermediate-scale quantum (NISQ) devices to fully fledged quantum computers.

Generalizing the matching decoder for the Chamon code [PDF]

open access: yesQuantum
Different choices of quantum error-correcting codes can reduce the demands on the physical hardware needed to build a quantum computer. To achieve the full potential of a code, we must develop practical decoding algorithms that can correct errors that ...

General entanglement-assisted quantum error-correcting codes

open access: yes, 2023
Entanglement-assisted quantum error-correcting codes (EAQECCs) make use of preexisting entanglement between the sender and receiver to boost the rate of transmission.

Fault-tolerant simulation of Lattice Gauge Theories with gauge covariant codes [PDF]

open access: yesQuantum
We show in this paper that a strong and easy connection exists between quantum error correction and Lattice Gauge Theories (LGT) by using the Gauge symmetry to construct an efficient error-correcting code for Abelian $\mathbb{Z_2}$ LGTs.

Entanglement renormalization, quantum error correction, and bulk causality

open access: yesJournal of High Energy Physics, 2017
Entanglement renormalization can be viewed as an encoding circuit for a family of approximate quantum error correcting codes. The logical information becomes progres-sively more well-protected against erasure errors at larger length scales. In particular,

Stabilizer Formalism for Operator Algebra Quantum Error Correction [PDF]

open access: yesQuantum
We introduce a stabilizer formalism for the general quantum error correction framework called operator algebra quantum error correction (OAQEC), which generalizes Gottesman's formulation for traditional quantum error correcting codes (QEC) and Poulin's ...

Superselection rules, quantum error correction, and quantum chromodynamics

open access: yesJournal of High Energy Physics
We investigate the relationship between superselection rules and quantum error correcting codes. We demonstrate that the existence of a superselection rule implies the Knill-Laflamme condition in quantum error correction.

Error Correcting Codes in Quantum Theory

open access: yesPhysical Review Letters, 1996
Summary: A new type of uncertainty relation is presented, concerning the information-bearing properties of a discrete quantum system. A natural link is then revealed between basic quantum theory and the linear error correcting codes of classical information theory.

Stability of gapped quantum matter and error-correction with adiabatic noise

open access: yesPhysical Review Research
The codespace of a quantum error-correcting code can often be identified with the degenerate ground space within a gapped phase of quantum matter. We argue that the stability of such a phase is directly related to a set of coherent error processes ...
