Monogamy of quantum steering in exciton--cavity optomechanical system
Hamza Harraf, Mohamed Amazioug, Rachid Ahl Laamara
In this work, we study a theoretical scheme to investigate the monogamy of quantum steering in a hybrid exciton--cavity optomechanical (EOM) system. Within the Gaussian-state forma…
Squeezed light and coherent feedback enhanced multiparameter quantum estimation in a double-cavity optomechanics: steady and dynamical states
Hamza Harraf, Mohamed Amazioug, Amjad Sohail +2
Multiparameter quantum estimation in open optomechanical systems is fundamentally constrained by dissipation, thermal fluctuations, and measurement incompatibility. In this work, w…
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…
