Enhanced multiparameter quantum estimation in cavity magnomechanics via a coherent feedback loop
Adnan Naimy, Abdallah Slaoui, Abderrahim Lakhfif +1
Multiparameter quantum metrology plays a fundamental role in uncovering and exploiting the distinctive features of quantum systems. In this work, we propose an effective and experi…
Optimal Multiparameter Quantum Estimation of Magnonic Couplings in a Magnomechanical Cavity
Adnan Naimy, Abdallah Slaoui, Abderrahim Lakhfif +1
In this work, we introduce an experimentally viable scheme to enhance the simultaneous estimation precision of the couplings and , with a particular focus on the p…
Parity symmetry breaking of spin- coherent state superpositions in Gaussian noise channel
Bouchra El Alaoui, Abdallah Slaoui, Abderrahim Lakhfif +1
The Wigner function and Wigner-Yanase skew information are connected through quantum coherence. States with high skew information often exhibit more pronounced negative regions in…
Bipartite and tripartite entanglement in an optomechanical ring cavity
Oumayma El Bir, Abderrahim Lakhfif, Abdallah Slaoui
Entanglement serves as a core resource for quantum information technologies, including applications in quantum cryptography, quantum metrology, and quantum communication. In this s…
