Pattern capacity of a single quantum perceptron
Fabio Benatti, Giovanni Gramegna, Stefano Mancini
Recent developments in Quantum Machine Learning have seen the introduction of several models to generalize the classical perceptron to the quantum regime. The capabilities of these…
Optimal control of a quantum sensor: A fast algorithm based on an analytic solution
S. Hernández-Gómez, F. Balducci, G. Fasiolo +3
Quantum sensors can show unprecedented sensitivities, provided they are controlled in a very specific, optimal way. Here, we consider a spin sensor of time-varying fields in the pr…
Entanglement propagation and dynamics in non-additive quantum systems
Guido Giachetti, Nicolo Defenu
The prominent collective character of long-range interacting quantum systems makes them promising candidates for quantum technological applications. Yet, lack of additivity overthr…
The Limit of the Entanglement Entropy
Giuseppe Mussardo, Jacopo Viti
Entangled quantum states share properties that do not have classical analogs, in particular, they show correlations that can violate Bell inequalities. It is therefore an interesti…
Underground test of gravity-related wave function collapse
S. Donadi, K. Piscicchia, C. Curceanu +3
Roger Penrose proposed that a spatial quantum superposition collapses as a back-reaction from spacetime, which is curved in different ways by each branch of the superposition. In t…
General Wick's Theorem for bosonic and fermionic operators
L. Ferialdi, L. Diósi
Wick's theorem provides a connection between time ordered products of bosonic or fermionic fields, and their normal ordered counterparts. We consider a generic pair of operator ord…
