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 …

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 …

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 …

Quantum information theory is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

Quantum information theory has considerably helped in the understanding of quantum many-
body systems. The role of quantum correlations and in particular, bipartite entanglement …

We explore the local quantum coherence and the local quantum uncertainty, based on
Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in …

The ability to live in coherent superpositions is a signature trait of quantum systems and
constitutes an irreplaceable resource for quantum-enhanced technologies. However …

Generalizing the quantifiers used to classify correlations in bipartite systems, we define
genuine total, quantum, and classical correlations in multipartite systems. The measure we …

In contrast with entanglement, as measured by concurrence, in general, quantum discord
does not possess the property of monogamy; that is, there is no tradeoff between the …

Correlations are a very important tool in the study of multipartite systems, for both classical
and quantum ones. The discussion about the quantum nature of correlations permeates …
