The Qubit Fidelity Under Different Error Mechanisms Based on Error Correction Threshold
Frontiers in Physics, 2022 Quantum error correction is a crucial step to realize large-scale universal quantum computing, and the condition for realizing quantum error correction is that the error probability of each operation step must below some threshold. This requires that the

Autonomous quantum error correction in a four-photon Kerr parametric oscillator
npj Quantum Information, 2022 Autonomous quantum error correction has gained considerable attention to avoid complicated measurements and feedback. Despite its simplicity compared with the conventional measurement-based quantum error correction, it is still a far from practical ...

Correlated errors in quantum-error corrections [PDF]
Physical Review A, 2001 We show that errors are not generated correlatedly provided that quantum bits do not directly interact with (or couple to) each other. Generally, this no-qubits-interaction condition is assumed except for the case where two-qubit gate operation is being performed.

Frontiers in Physics, 2022 Quantum error correction technology is a vital method to eliminate noise during the operation of quantum computers. To solve the problem caused by noise, in this paper, reinforcement learning is used to encode defects of Semion codes, and the experience ...

IEEE Access, 2020 Quantum information is prone to suffer from errors caused by the so-called decoherence, which describes the loss in coherence of quantum states associated to their interactions with the surrounding environment.

Quantum error correction under numerically exact open-quantum-system dynamics
Physical Review Research, 2023 The known quantum error-correcting codes are typically built on approximative open-quantum-system models such as Born-Markov master equations. However, it is an open question how such codes perform in actual physical systems that, to some extent ...

A Novel Approach for Asymmetric Quantum Error Correction With Syndrome Measurement
IEEE Access, 2022 Most of the quantum error correction methods are symmetric. Symmetric methods are implemented by considering the amplitude of bit flip(X) and phase flip(Z) errors as same.

Correcting Quantum Errors with Entanglement [PDF]
Science, 2006 We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error–correcting codes, thus allowing us to “quantize” all of classical linear coding theory.
