Operator quantum error correction [PDF]

open access: yesQuantum Information and Computation, 2006
This paper is an expanded and more detailed version of the work \cite{KLP04} in which the Operator Quantum Error Correction formalism was introduced. This is a new scheme for the error correction of quantum operations that incorporates the known techniques --- i.e.

Algebraic and information-theoretic conditions for operator quantum error-correction [PDF]

open access: yes, 2005
Operator quantum error-correction is a technique for robustly storing quantum information in the presence of noise. It generalizes the standard theory of quantum error-correction, and provides a unified framework for topics such as quantum error ...

Non-Pauli topological stabilizer codes from twisted quantum doubles [PDF]

open access: yesQuantum, 2021
It has long been known that long-ranged entangled topological phases can be exploited to protect quantum information against unwanted local errors. Indeed, conditions for intrinsic topological order are reminiscent of criteria for faithful quantum error ...

Perturbative Quantum Error Correction [PDF]

open access: yesPhysical Review Letters, 2011
We derive simple necessary and sufficient conditions under which a quantum channel obtained from an arbitrary perturbation from the identity can be reversed on a given code to the lowest order in fidelity. We find the usual Knill-Laflamme conditions applied to a certain operator subspace which, for a generic perturbation, is generated by the Lindblad ...

Embedded quantum-error correction and controlled-phase gate for molecular spin qubits

open access: yesAIP Advances, 2021
A scalable architecture for quantum computing requires logical units supporting quantum-error correction. In this respect, magnetic molecules are particularly promising, since they allow one to define logical qubits with embedded quantum-error correction

Quantum Error Correction For Dummies

open access: yes2023 IEEE International Conference on Quantum Computing and Engineering (QCE), 2023
In the current Noisy Intermediate Scale Quantum (NISQ) era of quantum computing, qubit technologies are prone to imperfections, giving rise to various errors such as gate errors, decoherence/dephasing, measurement errors, leakage, and crosstalk. These errors present challenges in achieving error-free computation within NISQ devices. A proposed solution

Learning time-dependent noise to reduce logical errors: real time error rate estimation in quantum error correction

open access: yesNew Journal of Physics, 2017
Quantum error correction is important to quantum information processing, which allows us to reliably process information encoded in quantum error correction codes. Efficient quantum error correction benefits from the knowledge of error rates.

Practical limits of error correction for quantum metrology

open access: yesNew Journal of Physics, 2021
Noise is the greatest obstacle in quantum metrology that limits it achievable precision and sensitivity. There are many techniques to mitigate the effect of noise, but this can never be done completely.
