Publikováno v: Journal of the Optical Society of America B. 40:1599
Recently, the Hilbert–Schmidt speed, as a special class of quantum statistical speed, has been reported to improve interferometric phase in a single-parameter quantum estimation. Here, we test this concept in the multiparameter scenario where two l

Improving the probabilistic quantum teleportation efficiency of arbitrary superposed coherent state using multipartite even and odd j-spin coherent states as resource
Autor: Meryem El Kirdi, Abdallah Slaoui, Hanane El Hadfi, Mohammed Daoud
Quantum teleportation is one of the most important techniques for quantum information secure transmission. Using preshared entanglement, quantum teleportation is designed as a basic key in many quantum information tasks and features prominently in qu

Enhancing the estimation precision of an unknown phase shift in multipartite Glauber coherent states via skew information correlations and local quantum Fisher information
Autor: Mehdi El Bakraoui, Abdallah Slaoui, Hanane El Hadfi, Mohammed Daoud
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 paper, we study these quantifiers in the case of multipartite Glauber

Dynamic of quantum Fisher information and quantum interferometric power in multipartite coherent states
Autor: Hanane El Hadfi, Rachid Laghmach, Wiam Kaydi, Mohammed Daoud
Publikováno v: The European Physical Journal D. 73
We examine the role of quantum correlations, contained multipartite Glauber coherent states, in enhancing the precision in the estimation of an unknown phase shift. We give the explicit form of quantum Fisher information in even and odd multipartite
