Automatic Quantum Error Correction [PDF]
Physical Review Letters, 1999 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 ...

Learning time-dependent noise to reduce logical errors: real time error rate estimation in quantum error correction [PDF]
New Journal of Physics, 2017 Quantum error correction is important to quantum information processing, which allows us to reliably process information encoded in quantum error correction codes. Efficient quantum error correction benefits from the knowledge of error rates.

Algebraic and information-theoretic conditions for operator quantum error-correction [PDF]
Phys. Rev. A 064304(R) (2007), 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 ...

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.

Continuous quantum error correction [PDF]
SPIE Proceedings, 2005 We describe new implementations of quantum error correction that are continuous in time, and thus described by continuous dynamical maps. We evaluate the performance of such schemes using numerical simulations, and comment on the effectiveness and ...

Analog quantum error correction [PDF]
Physical Review Letters, 1997 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 ...
