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

In this Letter, we show that the Shore-Johnson axioms for the maximum entropy principle in
statistical estimation theory account for a considerably wider class of entropic functional than …

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

It was shown that the particle distribution detected by a uniformly accelerated observer in the
inertial vacuum (Unruh effect) deviates from the pure Planckian spectrum when considering …

Flavor mixing of quantum fields was found to be responsible for the breakdown of the
thermality of Unruh effect. Recently, this result was revisited in the context of nonextensive …

The uncertainty of a mixed state has two quite different origins: classical mixing and
quantum randomness. While the classical aspect (mixedness) is significantly quantified by …

In its most basic form, decision-making can be viewed as a computational process that
progressively eliminates alternatives, thereby reducing uncertainty. Such processes are …

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 …

We analyze the problem of quantifying entanglement in pure and mixed states of fermionic
systems with a fixed number parity yet not necessarily a fixed particle number. The mode …

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 …
