Coherent feedback-enhanced asymmetry of thermal process in open quantum systems: Cavity optomechanics
Hamza Harraf, Mohamed Amazioug, Rachid Ahl Laamara
Entropy production is a fundamental concept in nonequilibrium thermodynamics, providing a direct measure of the irreversibility inherent in any physical process. In this work, we i…
Magnon-rotation enhanced nonreciprocity of multipartite entanglement in a magnomechanical system
Hamza Harraf, Noura Chabar, Mohamed Amazioug +2
Nonreciprocal physics is attracting significant interest in quantum information processing. In this work, we propose a scheme to investigate the nonreciprocity of bi- and tripartit…
Monogamy of Gaussian quantum steering and entanglement in a hybrid qubit-cavity optomagnonic system with coherent feedback loop
Hamza Harraf, Mohamed Amazioug, Amjad Sohail +1
The monogamy of quantum correlations is a fundamental principle in quantum information processing, limiting how quantum correlations can be shared among multiple subsystems. Here w…
Extracted work as measure of entanglement in optomechanics
Hamza Harraf, M'bark Amghar, Wiam Kaydi +2
In this work, we investigate quantum entanglement and work extraction in two distinct optomechanical systems. The first system consists of two spatially separated Fabry-Pérot cavit…
Quantum synchronization and entanglement of two magnon modes in a magnomechanical system
Hamza Harraf, Mohamed Amazioug, Rachid Ahl Laamara
We investigate theoretically the improvement of the entanglement between the indirectly coupled two magnon modes in a magnomechanical system with magnon squeezing. We quantify the…
