Pseudo quantum advantages in perceptron storage capacity
Fabio Benatti, Masoud Gharahi, Giovanni Gramegna +2
We investigate a generalized quantum perceptron architecture characterized by an oscillating activation function with a tunable frequency ranging from zero to infinity. Employing a…
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.…
Open harmonic chain without secular approximation
Melika Babakan, Fabio Benatti, Laleh Memarzadeh
We study particle and energy transport in an open quantum system consisting of a three harmonic oscillator chain coupled to thermal baths at different temperatures placed at the en…
An open harmonic chain: Exact vs global and local reduced dynamics
Melika Babakan, Fabio Benatti, Laleh Memarzadeh
In the following, we study the dissipative time-evolution of a quantum chain consisting of three coupled harmonic oscillators, the first and third of which weakly interact quadrati…
