It is proved that, for any bipartite steerable state, there are instances of the quantum subchannel discrimination problem for which this state allows a correct discrimination with strictly higher probability than in the absence of entanglement, even when measurements are restricted to local measurements aided by one-way communication.Expand

This work provides a more stringent formulation of both the uncertainty principle and the information exclusion principle, with direct applications for, e.g., the security analysis of quantum key distribution, entanglement estimation, and quantum communication.Expand

We prove that the correlations present in a multipartite quantum state have an operational quantum character even if the state is unentangled, as long as it does not simply encode a multipartite… Expand

The robustness of coherence is defined and proven to be a full monotone in the context of the recently introduced resource theories of quantum coherence, and the measure is shown to be observable.Expand

We argue that the geometric discord introduced in [B. Dakic, V. Vedral, and C. Brukner, Phys. Rev. Lett. 105, 190502 (2010)] is not a good measure for the quantumness of correlations, as it can… Expand

It is proved that the standard regularized entropy of entanglement is strictly positive for all multipartite entangled states, which implies that the asymptotic creation of a multipartites entangled state by means of local operations and classical communication always requires the consumption of a nonlocal resource at a strictly positive rate.Expand

Quantum states may exhibit asymmetry with respect to the action of a given group. Such an asymmetry of states can be considered as a resource in applications such as quantum metrology, and it is a… Expand

Quantum discord quantifies nonclassical correlations beyond the standard classification of quantum states into entangled and unentangled. Although it has received considerable attention, it still… Expand

A protocol in which general nonclassical multipartite correlations produce a physically relevant effect, leading to the creation of bipartite entanglement, emphasizing the key role of state mixedness in maximizing non classicality.Expand

The particular state, known to be 1-copy nondistillable and supposed to be bound entangled, is considered, and the problem of its two-copy distillability, which boils down to show that maximal overlap of some projector with Schmidt rank two states does not exceed 1/2 is studied.Expand
