Conditions for the approximate correction of algebras
Cédric Bény
We study the approximate correctability of general algebras of observables, which represent hybrid quantum-classical information. This includes approximate quantum error correcting…

General conditions for approximate quantum error correction and near-optimal recovery channels
Cédric Bény, Ognyan Oreshkov
We derive necessary and sufficient conditions for the approximate correctability of a quantum code, generalizing the Knill-Laflamme conditions for exact error correction. Our measu…

Information flow at the quantum-classical boundary
Cédric Bény
We study the nature of the information preserved by a quantum channel via the observables which exist in its image (in the Heisenberg picture), and can therefore be simulated on th…
