Quantumness of hybrid systems under quantum noise
M. Abdellaoui, N. -E. Abouelkhir, A. Slaoui +2
We investigate the quantum correlations in an axially symmetric hybrid qubit-qutrit system subjected to different noisy environments. We first introduce a physical model and analyz…
Quantum Phase Sensitivity with Generalized Coherent States Based on Deformed su(1,1) and Heisenberg Algebras
N. E. Abouelkhir, A. Slaoui, R. Ahl Laamara
We investigate the phase sensitivity of a Mach-Zehnder interferometer using a special class of generalized coherent states constructed from generalized Heisenberg and deformed $su(…
Quantum phase estimation and realistic detection schemes in Mach-Zehnder interferometer using SU(2) coherent states
Mohammed Abdellaoui, Nour-Eddine Abouelkhir, Abdallah Slaoui +1
In quantum parameter estimation, the quantum Cramér-Rao bound (QCRB) sets a fundamental limit on the precision achievable with unbiased estimators. It relates the uncertainty in es…
Enhancing phase sensitivity in Mach-Zehnder interferometer with various detection schemes using SU(1,1) coherent states
Nour-Eddine Abouelkhir, Abdallah Slaoui, El Hassan Saidi +2
Improving interferometric phase sensitivity is crucial for high-precision measurements in rapidly developing quantum technologies. The Mach-Zehnder interferometer (MZI) is a versat…
