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…
Dynamic Evolution of Quantum Fisher and Skew Information under Decoherence in Three-Qubit X-States
A. Naimy, A. Slaoui, A. Ali +3
Quantum metrology leverages quantum effects such as squeezing, entanglement, and other quantum correlations to boost precision in parameter estimation by saturating quantum Cramer…
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…
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…
Quantifying non-Markovianity via local quantum Fisher information
Yassine Dakir, Abdallah Slaoui, Lalla Btissam Drissi +1
Characterizing non-Markovianity in open quantum systems (OQSs) is gaining increasing attention due to its profound implications for quantum information processing. This phenomenon…
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…
Cyclic Quantum Teleportation of Two-Qubit Entangled States by using Six-Qubit Cluster State and Six-Qubit Entangled State
A. Slaoui, M. El Kirdi, R. Ahl Laamara +3
Cyclic quantum teleportation schemes requires at least the existence of three collaborators acting all as senders and receivers of quantum information, each one of them has an info…
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…
