A set of operators, the so-called k-fermion operators, that interpolate between boson and fermion operators are introduced through the consideration of an algebra arising from two non-commuting quonâ€¦ (More)

We propose a quantum key distribution protocol using Greenberger Horne Zeilinger tripartite coherent states. The sender and the receiver share similar key by exchanging the correlation coherentâ€¦ (More)

It is well known that quantum entanglement makes certain tasks in quantum information theory possible. However, there are also quantum tasks that display a quantum advantage without entanglement.â€¦ (More)

Generalized Zk-graded Grassmann variables are used to label coherent states related to the nilpotent representation of the q-oscillator of Biedenharn and Macfarlane when the deformation parameter isâ€¦ (More)

We review the notion of the deformation of the exterior wedge product. This allows us to construct the deformation of the algebra of exterior forms over a vector space and also over an arbitraryâ€¦ (More)

A dynamical algebra Aq, englobing many of the deformed harmonic oscillator algebras is introduced. One of its special cases is extensively developed. A general method for constructing coherent statesâ€¦ (More)

In this paper, we construct a covariant differential calculus on a quantum plane with two-parametric quantum group as a symmetry group. The two cases d 2 = 0 and d 3 = 0 are completely established.â€¦ (More)

The concurrence of a two-qubit nonorthogonal pure state is determined through the construction of this state in the language of spin coherent states. The generalization of this method to the case ofâ€¦ (More)
