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.

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.

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 ...

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

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

Practical limits of error correction for quantum metrology
New 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.

Triangular color codes on trivalent graphs with flag qubits
New Journal of Physics, 2020 The color code is a topological quantum error-correcting code supporting a variety of valuable fault-tolerant logical gates. Its two-dimensional version, the triangular color code, may soon be realized with currently available superconducting hardware ...

Measurement-based estimator scheme for continuous quantum error correction
Physical Review Research, 2022 Canonical discrete quantum error correction (DQEC) schemes use projective von Neumann measurements on stabilizers to discretize the error syndromes into a finite set, and fast unitary gates are applied to recover the corrupted information.

Fault-tolerant quantum computing in the Pauli or Clifford frame with slow error diagnostics [PDF]
Quantum, 2018 We consider the problem of fault-tolerant quantum computation in the presence of slow error diagnostics, either caused by measurement latencies or slow decoding algorithms.
