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

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.

Ability of stabilizer quantum error correction to protect itself from its own imperfection [PDF]
, 2014 The theory of stabilizer quantum error correction allows us to actively stabilize quantum states and simulate ideal quantum operations in a noisy environment.

Multidimensional Bose quantum error correction based on neural network decoder
npj Quantum Information, 2022 Boson quantum error correction is an important means to realize quantum error correction information processing. In this paper, we consider the connection of a single-mode Gottesman-Kitaev-Preskill (GKP) code with a two-dimensional (2D) surface (surface ...

Implementation of the Five Qubit Error Correction Benchmark [PDF]
, 2001 The smallest quantum code that can correct all one-qubit errors is based on five qubits. We experimentally implemented the encoding, decoding and error-correction quantum networks using nuclear magnetic resonance on a five spin subsystem of labeled ...

Theory of quasi-exact fault-tolerant quantum computing and valence-bond-solid codes
New Journal of Physics, 2022 In this work, we develop the theory of quasi-exact fault-tolerant quantum (QEQ) computation, which uses qubits encoded into quasi-exact quantum error-correction codes (‘quasi codes’).

Quantum minimal surfaces from quantum error correction
SciPost Physics, 2022 We show that complementary state-specific reconstruction of logical (bulk) operators is equivalent to the existence of a quantum minimal surface prescription for physical (boundary) entropies.
