The Lattice Schwinger Model and Its Quantum Simulation
Joao C. Pinto Barros, Pierpaolo Fontana, Pasquale Sodano +1
In this chapter we review results on the lattice Schwinger model. In par-ticular, we show how the effect of the anomaly is reproduced on the lattice. We connect these results to re…
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…
Diffusion Minimization via Optimal Smearing in Collapse and Hybrid Classical-Quantum Gravitational Models
Nicolò Piccione
Spontaneous diffusion (i.e., non-conservation of energy) is a prominent, testable prediction of collapse and hybrid classical-quantum gravitational models. Without smearing of the…
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…
Spontaneous Collapse Models
Matteo Carlesso, Sandro Donadi
Collapse models are phenomenological models introduced to solve the measurement problem in quantum mechanics. They modify the Schrödinger equation by adding non-linear and stochast…
Quench dynamics of entanglement entropy under projective charge measurements: the free fermion case
Riccardo Travaglino, Colin Rylands, Pasquale Calabrese
We consider the effect of projective measurements on the quench dynamics of the bipartite entanglement entropy in one dimensional free fermionic systems. In our protocol, we consid…
