Characterization of non-signaling correlations from mutual information
Ignacio Perito, Guido Bellomo, Daniel Galicer +3
We present a characterization of the set of non-signaling correlations in terms of a two dimensional representation that involves the maximal value of a Bell functional and the mut…
Impossibility of memory in hidden-signaling models for quantum correlations
Ignacio Perito, Guido Bellomo, Daniel Galicer +3
We consider a toy model for non-local quantum correlations in which nature resorts to some form of hidden signaling (i.e., signaling between boxes but not available to the users) t…
Extremal elements of a sublattice of the majorization lattice and approximate majorization
César Massri, Guido Bellomo, Federico Holik +1
Given a probability vector with its components sorted in non-increasing order, we consider the closed ball with formed by the probability vect…
Optimal common resource in majorization-based resource theories
G. M. Bosyk, G. Bellomo, F. Holik +2
We address the problem of finding the optimal common resource for an arbitrary family of target states in quantum resource theories based on majorization, that is, theories whose c…
Generalized entropies in quantum and classical statistical theories
M. Portesi, F. Holik, P. W. Lamberti +3
We study a version of the generalized (h, ϕ)-entropies, introduced by Salicrú et al, for a wide family of probabilistic models that includes quantum and classical statistical theor…
Lossless quantum data compression with exponential penalization: an operational interpretation of the quantum Rényi entropy
G. Bellomo, G. M. Bosyk, F. Holik +1
Based on the problem of quantum data compression in a lossless way, we present here an operational interpretation for the family of quantum Rényi entropies. In order to do this, we…
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…
Quantum information as a non-Kolmogorovian generalization of Shannon's theory
F. Holik, G. M. Bosyk, G. Bellomo
In this article we discuss the formal structure of a generalized information theory based on the extension of the probability calculus of Kolmogorov to a (possibly) non-commutative…
Quantum state space-dimension as a quantum resource
Angelo Plastino, Guido Bellomo, Angel R. Plastino
We argue that the dimensionality of the space of quantum systems' states should be considered as a legitimate resource for quantum information tasks. The assertion is supported by…
On a conjecture regarding Fisher information
Angelo Plastino, Guido Bellomo, Angel R. Plastino
Fisher's information measure plays a very important role in diverse areas of theoretical physics. The associated measures as functionals of quantum probability distributions define…
Quantum correlations from classically correlated states
Guido Bellomo, Ana P. Majtey, A. R. Plastino +1
Consider a bipartite quantum system with at least one of its two components being itself a composite system. By tracing over part of one (or both) of these two subsystems it is pos…
Classical extension of quantum-correlated separable states
Guido Bellomo, Angelo Plastino, Angel R. Plastino
Li and Luo [Phys. Rev. A 78 (2008), 024303] discovered a remarkable relation between discord and entanglement. It establishes that all separable states can be obtained via reductio…
Comment on "Quantum discord through the generalized entropy in bipartite quantum states"
Guido Bellomo, Angelo Plastino, Anna P. Majtey +1
In [X.-W. Hou, Z.-P. Huang, S. Chen, Eur. Phys. J. D 68, 1 (2014)], Hou et al. present, using Tsallis' entropy, possible generalizations of the quantum discord measure, finding ori…
Quantum to classical limit of open systems
Guido Bellomo, Mario Castagnino, Sebastian Fortin
We present a complete review of the quantum-to-classical limit of open systems by means of the theory of decoherence and the use of the Weyl-Wigner-Moyal (WWM) transformation. We s…
