Quantum discord for multipartite coherent states interpolating between Werner and Greenberger-Horne-Zeilinger states
M. Daoud, R. Ahl Laamara
The quantum discord is used as measure of quantum correlations for two families of multipartite coherent states. The first family interpolates between generalized GHZ states and ge…
Quantum discord of Bell cat-states under amplitude damping
M. Daoud, R. Ahl Laamara
The evolution of pairwise quantum correlations of Bell cat-states under amplitude damping is examined using the concept of quantum discord which goes beyond entanglement. A closed…
Entangled Phase States via Quantum Beam Splitter
M. Daoud, E. B. Choubabi
We study the entanglement effect of beam splitter on the temporally stable phase states. Specifically, we consider the eigenstates (phase states) of an unitary phase operator resul…
Three dimensional quantum key distribution in the presence of several eavesdroppers
M. Daoud, H. Ez-zahraouy
Quantum key distribution based on encoding in three dimensional systems in the presence of several eavesdroppers is proposed. This extends the BB84 protocol in the presence of many…
Bipartite entanglement of multipartite coherent states using quantum network of beam splitters
M. Daoud, E. B. Choubabi
We investigate the generation of multipartite entangled SU(k+1) coherent states using a quantum network involving a sequence of k beam splitters. We particularly investigate the en…
Bipartite and Tripartite Entanglement of Truncated Harmonic Oscillator Coherent States via Beam Splitters
M. Daoud, A. Jellal, E. B. Choubabi +1
We introduce a special class of truncated Weyl-Heisenberg algebra and discuss the corresponding Hilbertian and analytical representations. Subsequently, we study the effect of a qu…
Extended Weyl-Heisenberg algebra, phase operator, unitary depolarizers and generalized Bell states
M. Daoud, E. H. El Kinani
Finite dimensional representations of extended Weyl-Heisenberg algebra are studied both from mathematical and applied viewpoints. They are used to define unitary phase operator and…
Phase states and coherent states for generalized Weyl-Heisenberg algebras
Maurice Robert Kibler, Mohammed Daoud
This paper is concerned with the construction of phase operators, phase states, vector phase states, and coherent states for a generalized Weyl-Heisenberg algebra. This polynomial…
Generalized Coherent States for Polynomial Weyl-Heisenberg Algebras
Maurice Robert Kibler, Mohammed Daoud
It is the aim of this paper to show how to construct Perelomov and Barut-Girardello coherent states for a polynomial Weyl-Heisenberg algebra. This algebra depends on r parameters.…
