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 ...

Quantum Error Correction via Riemannian Optimisation [PDF]
, 2023 openA quantum error correction protocol consists of (1) a set of quantum states faithfully representing some logical information (the code), and (2) a recovery map that is able to correct the effect of environmental noise on such states.

Quantum Error Correction for Metrology [PDF]
Physical Review Letters, 2014 We propose and analyze a new approach based on quantum error correction (QEC) to improve quantum metrology in the presence of noise. We identify the conditions under which QEC allows one to improve the signal-to-noise ratio in quantum-limited measurements, and we demonstrate that it enables, in certain situations, Heisenberg-limited sensitivity.

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 ...

Motional quantum error correction [PDF]
Journal of Modern Optics, 2000 We examine the dynamics of a qubit stored in the motional degrees of freedom of an ultra-cold ion in an ion trap which is subject to the decoherence effects of a finite-temperature bath. We discover an encoding of the qubit, in two of the motional modes of the ion, which is stable against the occurrence of either none or one quantum jump.

Recovery in quantum error correction for general noise without measurement [PDF]
, 2011 It is known that one can do quantum error correction without syndrome measurement, which is often done in operator quantum error correction (OQEC). However, the physical realization could be challenging, especially when the recovery process involves high-

Quantum Error Correction for Communication
Physical Review Letters, 1996 We show how procedures which can correct phase and amplitude errors are in themselves sufficient to correct errors due to quantum entanglement, generalizing earlier results. We specify general criteria for quantum error correction, introduce quantum versions of the Hamming and the Gilbert-Varshamov bounds, and comment on the practical implementations ...
