Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

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 …

We consider multipartite states of qubits and prove that their bipartite quantum
entanglement, as quantified by the concurrence, satisfies a monogamy inequality …

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 …

We analyze the quantum phase transition in the Bose-Hubbard model borrowing two tools
from quantum-information theory, ie, the ground-state fidelity and entanglement measures …

The detection and certification of entanglement and quantum correlations in materials is of
fundamental and far‐reaching importance, and has seen significant recent progress. It …

For continuous-variable (CV) systems, we introduce a measure of entanglement, the CV
tangle (contangle), with the purpose of quantifying the distributed (shared) entanglement in …

We propose a new approach to study quantum phase transitions in low-dimensional lattice
models. It is based on studying the von Neumann entropy of two neighboring central sites in …

We derive a general relation between the nonanalyticities of the ground state energy and
those of a subclass of the multipartite generalized global entanglement (GGE) measure …
