Metaphors, generalizations and unifications are natural and desirable ingredients of the
evolution of scientific theories and concepts. Physics, in particular, obviously walks along …

Quantum Information Theory and the Foundations of Quantum Mechanics is a conceptual
analysis of one the most prominent and exciting new areas of physics, providing the first full …

We discuss the relationship between entropic uncertainty relations and entanglement. We
present two methods for deriving separability criteria in terms of entropic uncertainty …

We present a quantum version of the generalized (h, ϕ)(h, ϕ)-entropies, introduced by
Salicrú et al. for the study of classical probability distributions. We establish their basic …

This thesis is a contribution to the debate on the implications of quantum information theory
for the foundations of quantum mechanics. In Part 1, the logical and conceptual status of …

We present a model of discrete quantum evolution based on quantum correlations between
the evolving system and a reference quantum clock system. A quantum circuit for the model …

We discuss the relation between fermion entanglement and bipartite entanglement. We first
show that an exact correspondence between them arises when the states are constrained to …

We discuss some fundamental properties of discrete system-time history states. Such states
arise for a quantum reference clock of finite dimension and lead to a unitary evolution of …

We propose a general measure of nonclassical correlations for bipartite systems based on
generalized entropic functions and majorization properties. Defined as the minimum …

We discuss the necessity of using nonstandard boson operators for diagonalizing quadratic
bosonic forms which are not positive definite and its convenience for describing the temporal …
