Improved bounds in entropic uncertainty relations
Julio I. de Vicente, Jorge Sánchez-Ruiz
Entropic uncertainty relations place nontrivial lower bounds to the sum of Shannon information entropies for noncommuting observables. Here we obtain a novel lower bound on the ent…

Information entropy of Gegenbauer polynomials of integer parameter
Julio I. de Vicente, Silvia Gandy, Jorge Sánchez-Ruiz
The position and momentum information entropies of -dimensional quantum systems with central potentials, such as the isotropic harmonic oscillator and the hydrogen atom, depend…

Separability conditions from the Landau-Pollak uncertainty relation
Julio I. de Vicente, Jorge Sánchez-Ruiz
We obtain a collection of necessary (sufficient) conditions for a bipartite system of qubits to be separable (entangled), which are based on the Landau-Pollak formulation of the un…
