Magnetic Control of the Non-Hermitian Skin Effect in Two-Dimensional Lattices
Stefano Longhi
The non-Hermitian skin effect (NHSE) -- the anomalous boundary accumulation of an extensive number of bulk modes -- has emerged as a hallmark of non-Hermitian physics, with broad i…
Entanglement estimation of Werner states with a quantum extreme learning machine
Hajar Assil, Abderrahim El Allati, Gian Luca Giorgi
Quantum Extreme Learning Machines (QELMs) have emerged as a potent tool for various quantum information processing tasks. We present a QELM protocol for estimating the amount of en…
Quantum reservoir computing in Jaynes-Cummings models: Nonlinear memory and time-series prediction
Sreetama Das, Gian Luca Giorgi, Roberta Zambrini
We investigate quantum reservoir computing (QRC) using a hybrid qubit-boson system described by the Jaynes-Cummings (JC) Hamiltonian and its dispersive limit (DJC). These models pr…
Dynamical Phase Transitions in Open Quantum Walks
Stefano Longhi
Dynamical phase transitions in the relaxation behavior of stochastic quantum walks are investigated, focusing on systems where coherent unitary evolution is periodically interrupte…
Universal Statistics of Charges Exchanges in Non-Abelian Quantum Transport
Matteo Scandi, Gonzalo Manzano
We derive detailed and intergral fluctuation relations as well as a Thermodynamic Uncertainty Relation constraining the exchange statistics of an arbitrary number of non-commuting…
Solitons, chaos, and quantum phenomena: a deterministic approach to the Schrödinger equation
Damià Gomila
We show that the Schrödinger equation describes the ensemble mean dynamics of solitons in a Galilean invariant field theory where we interpret solitons as particles. On a zero back…
