Metaphors, generalizations and unifications are natural and desirable ingredients of the
evolution of scientific theories and concepts. Physics, in particular, obviously walks along …

We study entanglement properties of mixed density matrices obtained from combinatorial
Laplacians. This is done by introducing the notion of the density matrix of a graph. We …

The exciting new features of entanglement are burgeoning with revolutionary new advances
in the areas of quantum communication, quantum information processing and quantum …

A comparison is made of various searching procedures, based upon different entanglement
measures or entanglement indicators, for highly entangled multiqubits states. In particular …

It has been recently pointed out [V. Giovannetti, S. Lloyd, and L. Maccone, Europhys. Lett.
62, 615 (2003)] that, for certain classes of states, quantum entanglement enhances the …

We explore quantum uncertainty relations involving the Fisher information functionals I x and
I p evaluated, respectively, on a wavefunction Ψ (x) defined on a D-dimensional …

The concept of quantum speed limit-time (QSL) was initially introduced as a lower bound to
the time interval that a given initial state ψ I may need so as to evolve into a state orthogonal …

There exists an interesting relationship between entanglement and the time evolution of
composite quantum systems: quantum entanglement enhances the'speed'of evolution of …

We investigate the entanglement-related features of the eigenstates of two exactly soluble
atomic models: a one-dimensional three-electron Moshinsky model, and a three …

A first use of Kaniadakis entropy in the context of quantum information is presented. First we
show that (as all smooth and concave trace-form entropies) it exhibits some properties …
