Abstract
We analyze non-Markovian memory effects displayed by the quantum Brownian motion modelled as quantum harmonic oscillators coupled to a bath consisting of harmonic oscillators. We study the time evolution of fidelity, Petz-R\'enyi relative entropy and quantum entanglement for a family of 1-, 2- and 3-mode Gaussian states.
