Quantum Entanglement in -Spherium
I. V. Toranzo, A. R. Plastino, P. Sánchez-Moreno +1
There are very few systems of interacting particles (with continuous variables) for which the entanglement of the concomitant eigenfunctions can be computed in an exact, analytical…
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…
Dynamics of entanglement in systems of identical fermions undergoing decoherence
A. Valdés-Hernández, A. P. Majtey, A. R. Plastino
Information that is stored in quantum-mechanical systems can be easily lost because of the interaction with the environment in a process known as decoherence. Possible physical imp…
