Approximate recovery with locality and symmetry constraints
Cédric Bény, Zoltán Zimborás, Fernando Pastawski
Numerous quantum many-body systems are characterized by either fundamental or emergent constraints---such as gauge symmetries or parity superselection for fermions---which effectiv…

Quantum error correction on infinite-dimensional Hilbert spaces
Cédric Bény, Achim Kempf, David W. Kribs
We present a generalization of quantum error correction to infinite-dimensional Hilbert spaces. The generalization yields new classes of quantum error correcting codes that have no…

Unsharp pointer observables and the structure of decoherence
Cédric Bény
The theory of decoherence attempts to explain the emergent classical behaviour of a quantum system interacting with its quantum environment. In order to formalize this mechanism we…
