Maximally correlated multipartite quantum states
J. Batle, M. Casas, A. Plastino
We investigate quantum states that posses both maximum entanglement and maximum discord between the pertinent parties. Since entanglement (discord) is defined only for bipartite (t…
A discussion on the origin of quantum probabilities
Federico Holik, Angel Plastino, Manuel Sáenz
We study the origin of quantum probabilities as arising from non-boolean propositional-operational structures. We apply the method developed by Cox to non distributive lattices and…
Discording power of quantum evolutions
F. Galve, F. Plastina, M. G. A. Paris +1
We introduce the discording power of a unitary transformation, which assesses its capability to produce quantum discord, and analyze in detail the generation of discord by relevant…
Generalizing entanglement via informational invariance for arbitrary statistical theories
F. Holik, C. Massri, A. Plastino
Given an arbitrary statistical theory, different from quantum mechanics, how to decide which are the nonclassical correlations? We present a formal framework which allows for a def…
