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…

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…

Constructing Multipartite Planar Maximally Entangled States from Phase States and Quantum Secret Sharing Protocol

Lahoucine Bouhouch, Yassine Dakir, Abdallah Slaoui +1

In this paper, we explore the construction of Planar Maximally Entangled (PME) states from phase states. PME states form a class of -partite states in which any subset of adjace…

Effects of DM and KSEA interactions on entanglement, Fisher and Wigner-Yanase information correlations of two XYZ-Heisenberg-qubit states under a magnetic field

S. Gaidi, A. Slaoui, A-B. A. Mohamed +2

We employ entanglement negativity, local quantum uncertainty (LQU), and local quantum Fisher information (LQFI) to characterize thermal entanglement between two XYZ-Heisenberg-qubi…

Quantum unital Otto heat engines: using Kirkwood-Dirac quasi-probability for the engine's coherence to stay alive

Abdelkader El Makouri, Abdallah Slaoui, Rachid Ahl Laamara

In this work, we consider quantum unital Otto heat engines. The latter refers to the fact that both the unitaries of the adiabatic strokes and the source of the heat provided to th…
