Perturbative Quantum Error Correction [PDF]
Physical 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 ...

Encoding Error Correction in an Integrated Photonic Chip [PDF]
, 2023 Integrated photonics provides a versatile platform for encoding and processing quantum information. However, the encoded quantum states are sensitive to noise, which limits their capability to perform complicated quantum computations. Here, we use a five-

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

Analog Quantum Error Correction [PDF]
Physical Review Letters, 1998 Quantum error-correction routines are developed for continuous quantum variables such as position and momentum. The result of such analog quantum error correction is the construction of composite continuous quantum variables that are largely immune to the effects of noise and decoherence.

A branching space-times view on quantum error correction [PDF]
, 2007 In this paper we describe some first steps for bringing the framework of branching space-times to bear on quantum information theory. Our main application is 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.

Automatic Quantum Error Correction [PDF]
Physical Review Letters, 2000 Criteria are given by which dissipative evolution can transfer populations and coherences between quantum subspaces, without a loss of coherence. This results in a form of quantum error correction that is implemented by the joint evolution of a system and a cold bath. It requires no external intervention and, in principal, no ancilla.
