Observation of associative-memory retrieval and spin-glass phases on a photonic quantum simulator
Taira Giordani, Gennaro Zanfardino, Luca Leuzzi +16
Models of interacting complex systems provide the fundamental statistical physics reference frame for the study and the understanding of associative memories, machine learning, and…
Geometric measures of quantum nonlocality: characterization, quantification, and comparison by distances and operations
Gennaro Zanfardino, Wojciech Roga, Gianluigi Tartaglione +2
We introduce a geometric framework for studying Bell nonlocality in Hilbert space, where, for a given quantum state, nonlocality is quantified by the distance between the state and…
Multiphoton quantum simulation of the generalized Hopfield memory model
Gennaro Zanfardino, Stefano Paesani, Luca Leuzzi +5
In the present work, we introduce, develop, and investigate a connection between multiphoton quantum interference, a core element of emerging photonic quantum technologies, and Hop…
Chiral and flavor oscillations in quantum field theory
Massimo Blasone, Gennaro Zanfardino
Massive fermions produced through weak charged interactions possess a definite chirality, which is not conserved during free propagation, leading to chiral oscillations. Neutrinos…
Chiral and flavor oscillations in a hyperentangled neutrino state
Victor Bittencourt, Massimo Blasone, Gennaro Zanfardino
In addition to flavor oscillations, Dirac neutrinos also undergo the so-called chiral oscillations, a consequence of the free-particle dynamics under the Dirac equation. Such a tra…
Chiral oscillations in quantum field theory
Victor Bittencourt, Massimo Blasone, Gennaro Zanfardino
Dirac particles have two intrinsic degrees-of-freedom, helicity and chirality. While helicity is conserved in time, chirality is not constant under time evolution for massive parti…
