Detecting quantum many-body states with imperfect measuring devices
K. Uriostegui, C. Pineda, C. Chryssomalakos +2
We study a coarse-graining map arising from incomplete and imperfect addressing of particles in a multipartite quantum system. In its simplest form, corresponding to a two-qubit st…

Coarse-grained dynamics in quantum many-body systems using the maximum entropy principle
Adán Castillo, Carlos Pineda, Erick SebastÃan Navarrete +1
Starting from a coarse-grained map of a quantum many-body system, we construct the inverse map that assigns a microscopic state to a coarse-grained state based on the maximum entro…
