We review selected advances in the theoretical understanding of complex quantum many-
body systems with regard to emergent notions of quantum statistical mechanics. We cover …

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 …

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 …

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

Quantum mechanics predicts that measurements of incompatible observables carry a
minimum uncertainty which is independent of technical deficiencies of the measurement …

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 …

The existence of better-than-classical quantum information processing (QIP) models which
consume very little or no entanglement suggests that separable or weakly entangled states …

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 discord, a measure of genuinely quantum correlations, is generalized to
continuous variable systems. For all two-mode Gaussian states, we calculate analytically the …
