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…
