Mutually Unbiased Bases In 3 and 4 Dimensions Semi-quantum Key Distribution Protocol
Hasnaa Hajji, Morad El Baz
Semi-quantum key distribution is traditionally based on two-level quantum systems. In this paper, an unconditional security of a semi quantum key distribution protocol based on hig…
Long range entanglement in quantum dot systems under the Fermi-Hubbard approach
Sanaa Abaach, Mustapha Faqir, Morad EL Baz
In the present paper we are interested in analyzing the pairwise entanglement in quantum dots, as ququart systems, naturally described by the Fermi-Hubbard model. Using the lower b…
Quantum correlations under the effect of a thermal environment in a triangular optomechanical cavity
Oumayma El Bir, Morad El Baz
We quantify the stationary correlations between the optical mode and the relative mechanical mode of a ring cavity composed of a fixed mirror and two movable ones in a triangular d…
Coherent state quantization of paragrassmann algebras
M. El Baz, R. Fresneda, J. P. Gazeau +1
By using a coherent state quantization of paragrassmann variables, operators are constructed in finite Hilbert spaces. We thus obtain in a straightforward way a matrix representati…
