The coherent superposition of states, in combination with the quantization of observables,
represents one of the most fundamental features that mark the departure of quantum …

Quantum coherence and quantum correlations are of fundamental and practical significance
for the development of quantum mechanics. They are also cornerstones of quantum …

This topical review article gives an overview of the interplay between quantum information
theory and thermodynamics of quantum systems. We focus on several trending topics …

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Recent results in quantum information theory characterize quantum coherence in the context
of resource theories. Here, we study the relation between quantum coherence and quantum …

Within the unified framework of exploiting the relative entropy as a distance measure of
quantum correlations, we make explicit the hierarchical structure of quantum coherence …

The field of classical stochastic processes forms a major branch of mathematics. Stochastic
processes are, of course, also very well studied in biology, chemistry, ecology, geology …

Quantum discord characterizes “nonclassicality” of correlations in quantum mechanics. It
has been proposed as the key resource present in certain quantum communication tasks …

We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …
