Quantumness and the role of locality on quantum correlations
Guido Bellomo, Angelo Plastino, Angel R. Plastino
Quantum correlations in a physical system are usually studied with respect to a unique (fixed) decomposition of the system into subsystems, without fully exploiting the rich struct…
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…
On the connection between Complementarity and Uncertainty Principles in the Mach-Zehnder interferometric setting
G. M. Bosyk, M. Portesi, F. Holik +1
We revisit, in the framework of Mach-Zehnder interferometry, the connection between the complementarity and uncertainty principles of quantum mechanics. Specifically, we show that,…
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…
On the lattice structure of probability spaces in quantum mechanics
Federico Holik, César Massri, Leandro Zuberman +1
Let C be the set of all possible quantum states. We study the convex subsets of C with attention focused on the lattice theoretical structure of these convex subsets and, as a resu…
Quantal effects and MaxEnt
Federico Holik, Angel Plastino
Convex operational models (COMs) are considered as great extrapolations to larger settings of any statistical theory. In this article we generalize the maximum entropy principle (M…
Entropic Entanglement Criteria for Fermion Systems
C. Zander, A. R. Plastino, M. Casas +1
Entanglement criteria for general (pure or mixed) states of systems consisting of two identical fermions are introduced. These criteria are based on appropriate inequalities involv…
Some features of the state-space trajectories followed by robust entangled four-qubit states during decoherence
A. P. Majtey, A. Borras, A. R. Plastino +2
In a recent work (Borras et al., Phys. Rev. A {\bf 79}, 022108 (2009)), we have determined, for various decoherence channels, four-qubit initial states exhibiting the most robust p…
Entanglement and the Quantum Brachistochrone Problem
A. Borras, C. Zander, A. R. Plastino +2
Entanglement is closely related to some fundamental features of the dynamics of composite quantum systems: quantum entanglement enhances the "speed" of evolution of certain quantum…
