Quantum Dynamical Entropy and Dissipative Information Flows
Giovanni Nichele, Fabio Benatti
The Alicki-Lindblad-Fannes dynamical (ALF) entropy measures the rate at which new information is gathered about a quantum system by inspecting its long-time evolution. We propose a…
Quantum Dynamical Entropy and non-Markovianity: a collisional model perspective
Giovanni Nichele, Fabio Benatti
Accessing the physical mechanisms behind non-Markovian phenomena in open quantum dynamics requires the study of the statistical properties of the joint system-environment dynamics.…
Superactivation of memory effects in a classical Markov environment
Fabio Benatti, Giovanni Nichele
We investigate a phenomenon known as Superactivation of Backflow of Information (SBFI); namely, the fact that the tensor product of a non-Markovian dynamics with itself exhibits Ba…
Quantum versus classical -divisibility
Fabio Benatti, Dariusz ChruÅciÅski, Giovanni Nichele
-divisibility is a central concept in both classical and quantum non-Markovian processes; in particular, it is strictly related to the notion of information backflow. When restr…
