Asymptotic non-Markovianity

Abstract

We investigate the asymptotic dynamics of exact quantum Brownian motion. We find that non-Markovianity can persist in the long-time limit, and that in general the asymptotic behaviour depends strongly on the system-environment coupling and the spectral density of the bath.

arXiv commentThe paper contains misleading statements on the behavior of quantum channels in the asymptotic regime, in relation with the enhancement of quantum technology tasks. It is completely superseded and replaced by arXiv:1804.03095
