Classical pair of states as optimal pair for quantum distinguishability quantifiers
Bassano Vacchini, Andrea Smirne, Nina Megier
The capability to quantitatively distinguish quantum states is of great importance for a variety of tasks, and has recently played an important role in the study of quantum reduced…
On the use of total state decompositions for the study of reduced dynamics
Andrea Smirne, Nina Megier, Bassano Vacchini
The description of the dynamics of an open quantum system in the presence of initial correlations with the environment needs different mathematical tools than the standard approach…
Correlations, information backflow, and objectivity in a class of pure dephasing models
Nina Megier, Andrea Smirne, Steve Campbell +1
We critically examine the role that correlations established between a system and fragments of its environment play in characterising the ensuing dynamics. We employ a class of dep…
Memory effects in quantum dynamics modelled by quantum renewal processes
Nina Megier, Manuel Ponzi, Andrea Smirne +1
Simple, controllable models play an important role to learn how to manipulate and control quantum resources. We focus here on quantum non-Markovianity and model the evolution of op…
Entropic bounds on information backflow
Nina Megier, Andrea Smirne, Bassano Vacchini
In the dynamics of open quantum systems, the backflow of information to the reduced system under study has been suggested as the actual physical mechanism inducing memory and thus…
On the connection between microscopic description and memory effects in open quantum system dynamics
Andrea Smirne, Nina Megier, Bassano Vacchini
The exchange of information between an open quantum system and its environment allows us to discriminate among different kinds of dynamics, in particular detecting memory effects t…
