Measures of quantum synchronization in continuous variable systems

A Mari, A Farace, N Didier, V Giovannetti, R Fazio - Physical review letters, 2013 - APS
We introduce and characterize two different measures which quantify the level of
synchronization of coupled continuous variable quantum systems. The two measures allow …

Quantum synchronization of a driven self-sustained oscillator

S Walter, A Nunnenkamp, C Bruder - Physical review letters, 2014 - APS
Synchronization is a universal phenomenon that is important both in fundamental studies
and in technical applications. Here we investigate synchronization in the simplest quantum …

Global topological synchronization on simplicial and cell complexes

T Carletti, L Giambagli, G Bianconi - Physical review letters, 2023 - APS
Topological signals, ie, dynamical variables defined on nodes, links, triangles, etc. of higher-
order networks, are attracting increasing attention. However, the investigation of their …

Dissipation as a resource for Quantum Reservoir Computing

A Sannia, R Martínez-Peña, MC Soriano, GL Giorgi… - Quantum, 2024 - quantum-journal.org
Dissipation induced by interactions with an external environment typically hinders the
performance of quantum computation, but in some cases can be turned out as a useful …

Quantum-like states on complex synchronized networks

GD Scholes - Proceedings of the Royal Society A, 2024 - royalsocietypublishing.org
Recent work has exposed the idea that interesting quantum-like (QL) probability laws,
including interference effects, can be manifest in classical systems. Here, we propose a …

Entanglement tongue and quantum synchronization of disordered oscillators

TE Lee, CK Chan, S Wang - Physical Review E, 2014 - APS
We study the synchronization of dissipatively coupled van der Pol oscillators in the quantum
limit, when each oscillator is near its quantum ground state. Two quantum oscillators with …

Polaritons and excitons: Hamiltonian design for enhanced coherence

GD Scholes - Proceedings of the Royal Society A, 2020 - royalsocietypublishing.org
The primary questions motivating this report are: Are there ways to increase coherence and
delocalization of excitation among many molecules at moderate electronic coupling …

Squeezing enhances quantum synchronization

S Sonar, M Hajdušek, M Mukherjee, R Fazio, V Vedral… - Physical review …, 2018 - APS
It is desirable to observe synchronization of quantum systems in the quantum regime,
defined by the low number of excitations and a highly nonclassical steady state of the self …
