Quantum correlations and mutual synchronization
Gian Luca Giorgi, Fernando Galve, Gonzalo Manzano, Pere Colet, and, Roberta Zambrini
TL;DR
This paper investigates how two detuned quantum harmonic oscillators can spontaneously synchronize due to environmental dissipation, with synchronization linked to decay rates and sustained quantum correlations like discord and mutual information.
Contribution
It identifies the conditions under which quantum oscillators synchronize and shows this is associated with persistent quantum correlations, advancing understanding of quantum synchronization phenomena.
Findings
Synchronization occurs under specific decay rate conditions.
Quantum discord and mutual information remain robust during synchronization.
Synchronization prevents information leakage from the system.
Abstract
We consider the phenomenon of mutual synchronization in a fundamental quantum system of two detuned quantum harmonic oscillators dissipating into the environment. We identify the conditions leading to this spontaneous phenomenon showing that the ability of the system to synchronize is related to the existence of disparate decay rates and is accompanied by robust quantum discord and mutual information between the oscillators, preventing the leak of information from the system.
