Journal ArticleDOI
Joint Measurability, Einstein-Podolsky-Rosen Steering, and Bell Nonlocality
TL;DR: It is shown that a set of measurements is not jointly measurable if and only if it can be used for demonstrating Einstein-Podolsky-Rosen steering, a form of quantum nonlocality, and shown that it does not violate a large class of Bell inequalities.
Journal ArticleDOI
One-way Einstein-Podolsky-Rosen Steering
TL;DR: In this article, a simple class of entangled two-qubit states which are one-way steerable, considering arbitrary projective measurements, is presented, which shows that the nonlocal properties of entangled states can be fundamentally asymmetrical.
Journal ArticleDOI
Inequivalence of entanglement, steering, and Bell nonlocality for general measurements

TL;DR: In this paper, it was shown that entanglement, one-way steering, two-way and non-localization are genuinely different considering general measurements, i.e., single round positive-operator-valued measures.
Journal ArticleDOI
All noncontextuality inequalities for the n-cycle scenario
Mateus Araújo,Mateus Araújo,Marco Túlio Quintino,Marco Túlio Quintino,Costantino Budroni,Costantino Budroni,Marcelo Terra Cunha,Adán Cabello,Adán Cabello +8 more
TL;DR: This work provides the complete characterization of the classical correlations and the corresponding maximal quantum violations for the case of n >= 4 observables X_0, ...,X_{n-1}, where each consecutive pair {X_i, X_{i+1}}, sum modulo n, is jointly measurable.
Journal ArticleDOI
Genuine hidden quantum nonlocality.
TL;DR: This work presents a class of two-qubit entangled states, for which a local model is constructed for the most general local measurements, and shows that the states violate a Bell inequality after local filtering.
