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

We analyze the general nonclassicality of correlations of a composite quantum system as
measured by the negativity of quantumness. The latter corresponds to the minimum …

We investigate and compare three distinguished geometric measures of bipartite quantum
correlations that have been recently introduced in the literature: the geometric discord, the …

We propose a characterization and a quantification of the general quantum correlation
which is exhibited even by a separable (unentangled) mixed bipartite state in terms of the …

We investigate a family of qubit-oscillator states as resources for hybrid quantum
communication. They result from a mechanism of qubit-controlled displacement on the …

The interferometric power of a bipartite quantum state quantifies the precision, measured by
quantum Fisher information, that such a state enables for the estimation of a parameter …

Quantum channels, in general, will disturb quantum states and will lead to decoherence (ie,
information leakage to the environment). For bipartite systems, local channels often cause …

We propose a modified metric based on the Hilbert–Schmidt norm and adopt it to define a
rescaled version of the geometric measure of quantum discord. Such a measure is found not …
