Controlling Stationary One-Way Steering via Thermal Effects in Optomechanics
Jamal El Qars, Mohammed Daoud, Rachid Ahl Laamara
Quantum steering is a kind of quantum correlations stronger than entanglement but weaker than Bell-nonlocality. In an optomechanical system pumped by squeezed light and driven in t…

Non-classical correlations in a two-mode optomechanical system
J. El Qars, M. Daoud, R. Ahl Laamara
The pairwise quantum correlations in a tripartite optomechanical system comprising a mechanical mode and two optical modes are analyzed. The Simon criterion is used as a witness of…

Quantifying quantumness of correlations using Gaussian Rényi-2 entropy in optomechanical interfaces
Jamal El Qars, Mohammed Daoud, Rachid Ahl Laamara
Using the Gaussian Rényi-2 entropy, we analyse the behaviour of two different aspects of quantum correlations (entanglement and quantum discord) in two optomechanical subsystems (o…
