Controlling multiparameter quantum estimation in exciton-optomechanics system
Hamza Harraf, Mohamed Amazioug, Rachid Ahl Laamara
Multiparameter quantum estimation has emerged as a central task in quantum metrology. In this work, we investigate multiparameter quantum estimation in a hybrid exciton--optomechan…
Squeezed-Light-Enhanced Multiparameter Quantum Estimation in Cavity Magnonics
Hamza Harraf, Mohamed Amazioug, Rachid Ahl Laamara
Improving multiparameter quantum estimation in magnonic systems via quantum noise suppression is a well-established and critical research objective. In this work, we propose an exp…
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 cavi…
