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…
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…
Achieving quantum metrological performance and exact Heisenberg limit precision through superposition of -spin coherent states
Hanan Saidi, Hanane El Hadfi, Abdallah Slaoui +1
In quantum phase estimation, the Heisenberg limit provides the ultimate accuracy over quasi-classical estimation procedures. However, realizing this limit hinges upon both the dete…
Estimating phase parameters of a three-level system interacting with two classical monochromatic fields in simultaneous and individual metrological strategies
Nour-Eddine Abouelkhir, Abdallah Slaoui, Hanane El Hadfi +1
Recently, the Hilbert-Schmidt speed, as a special class of quantum statistical speed, has been reported to improve the interferometric phase in single-parameter quantum estimation.…
A simple analytical expression of quantum Fisher and Skew information and their dynamics under decoherence channels
Nour-Eddine Abouelkhir, Hanane EL Hadfi, Abdallah Slaoui +1
In statistical estimation theory, it has been shown previously that the Wigner-Yanase skew information is bounded by the quantum Fisher information associated with the phase parame…
Improving the probabilistic quantum teleportation efficiency of arbitrary superposed coherent state using multipartite even and odd j-spin coherent states as resource
Meryem El Kirdi, Abdallah Slaoui, Hanane El Hadfi +1
Quantum teleportation is one of the most important techniques for quantum information secure transmission. Using preshared entanglement, quantum teleportation is designed as a basi…
Enhancing the estimation precision of an unknown phase shift in multipartite Glauber coherent states via skew information correlations and local quantum Fisher information
Mehdi El Bakraoui, Abdallah Slaoui, Hanane El Hadfi +1
Local quantum uncertainty (LQU) and local quantum Fisher information (LQFI) are both two tools used to capture purely quantum correlations in multi-partite quantum systems. In this…
Quantum discord in photon added Glauber coherent states of -type
M. Daoud, W. Kaydi, H. El Hadfi
We investigate the influence of photon excitations on quantum correlations in tripartite Glauber coherent states of Greenberger-Horne-Zeilinger type. The pairwise correlations are…
Pairwise quantum and classical correlations in multi-qubits states via linear relative entropy
M. Daoud, R. Ahl Laamara, H. El Hadfi
The pairwise correlations in a multi-qubit state are quantified through a linear variant of relative entropy. In particular, we derive the explicit expressions of total, quantum an…
