Multimedia security is extremely significant concern for the internet technology because of the ease of the duplication, distribution and manipulation of the multimedia data. The digital watermarkingâ€¦ (More)

We show that trace distance measure of coherence is a strong monotone for all qubit and, so called, X states. An expression for the trace distance coherence for all pure states and a semi definiteâ€¦ (More)

Heavy metal contamination of soil resulting from sewage irrigation is a cause of serious concern due to the potential health impacts of consuming contaminated products. In this study an assessmentâ€¦ (More)

Multiparametric quantum deformations of gl(2) are studied through a complete classification of gl(2) Lie bialgebra structures. From them, the nonrelativistic limit leading to harmonic oscillator Lieâ€¦ (More)

The nonlocal properties for a kind of generic N -dimensional bipartite quantum systems are investigated. A complete set of invariants under local unitary transformations is presented. It is shownâ€¦ (More)

We establish the non-existence of a universal Hadamard gate for arbitrary unknown qubits, by considering two different principles; namely, no-superluminal signalling and non-increase of entanglementâ€¦ (More)

All Lie bialgebra structures for the (1+ 1)-dimensional centrally extended SchrÃ¶dinger algebra are explicitly derived and proved to be of the coboundary type. Therefore, since all of them come from aâ€¦ (More)

All Lie bialgebra structures on the Heisenbergâ€“Weyl algebra [A+, Aâˆ’] = M are classified and explicitly quantized. The complete list of quantum Heisenbergâ€“Weyl algebras so obtained includes newâ€¦ (More)

A two-parametric non-standard (Jordanian) deformation of the Lie algebra gl(2) is constructed, and then, exploited to obtain a new, triangular R-matrix solution of the coloured Yang-Baxter equation.â€¦ (More)
