The classical-quantum boundary for correlations:<? format?> Discord and related measures

K Modi, A Brodutch, H Cable, T Paterek, V Vedral - Reviews of Modern Physics, 2012 - APS
One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Open quantum systems with local and collective incoherent processes: Efficient numerical simulations using permutational invariance

N Shammah, S Ahmed, N Lambert, S De Liberato… - Physical Review A, 2018 - APS
The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

Quantum many-body dynamics in optomechanical arrays

M Ludwig, F Marquardt - Physical review letters, 2013 - APS
We study the nonlinear driven dissipative quantum dynamics of an array of optomechanical
systems. At each site of such an array, a localized mechanical mode interacts with a laser …

Algebraic theory of quantum synchronization and limit cycles under dissipation

B Buča, C Booker, D Jaksch - SciPost Physics, 2022 - scipost.org
Synchronization is a phenomenon where interacting particles lock their motion and display
non-trivial dynamics. Despite intense efforts studying synchronization in systems without …

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
