Witnessing non-Markovian dynamics through correlations
Dario De Santis, Markus Johansson, Bogna Bylicka +2
Non-Markovian effects in an open-system dynamics are usually associated to information backflows from the environment to the system. However, the way these backflows manifest and h…
Continuous Monitoring of Energy in Quantum Open Systems
Gabriel P. Martins, Nadja K. Bernardes, Marcelo F. Santos
We propose a method to continually monitor the energy of a quantum system. We show that by having some previous knowledge of the system's dynamics, but not all of it, one can use t…
A correlation measure detecting almost all non-Markovian evolutions
Dario De Santis, Markus Johansson, Bogna Bylicka +2
We investigate the ability of correlation measures to witness non-Markovian open quantum system dynamics. It is shown that the mutual information and any entanglement measure betwe…
Coarse graining a non-Markovian collisional model
Nadja K. Bernardes, Andre R. R. Carvalho, C. H. Monken +1
The dynamics of systems subjected to noise is called Markovian in the absence of memory effects, i.e. when its immediate future only depends on its present. Time correlations in th…
Rate analysis for a hybrid quantum repeater
Nadja K. Bernardes, Ludmiła Praxmeyer, Peter van Loock
We present a detailed rate analysis for a hybrid quantum repeater assuming perfect memories and using optimal probabilistic entanglement generation and deterministic swapping routi…
