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 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 e…
