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…
Evolution equations for quantum semi-Markov dynamics
Nina Megier, Andrea Smirne, Bassano Vacchini
Using a newly introduced connection between the local and non-local description of open quantum system dynamics, we investigate the relationship between these two characterisations…
Rate operator unravelling for open quantum system dynamics
Andrea Smirne, Matteo Caiaffa, Jyrki Piilo
Stochastic methods with quantum jumps are often used to solve open quantum system dynamics. Moreover, they provide insight into fundamental topics, as the role of measurements in q…
The interplay between local and non-local master equations: exact and approximated dynamics
Nina Megier, Andrea Smirne, Bassano Vacchini
Master equations are a useful tool to describe the evolution of open quantum systems. In order to characterize the mathematical features and the physical origin of the dynamics, it…
