In recent years, the use of information principles to understand quantum correlations has been very successful. Unfortunately, all principles considered so far have a bipartite formulation, but intrinsically multipartite principles, yet to be discovered, are necessary for reproducing quantum correlations. Here we introduce local orthogonality, an intrinsically multipartite principle stating that events involving different outcomes of the same local measurement must be exclusive or orthogonal… 
Exploring the Local Orthogonality Principle
Nonlocality is arguably one of the most fundamental and counterintuitive aspects of quantum theory. Nonlocal correlations could, however, be even more nonlocal than quantum theory allows, while still
Local Quantum Measurement Demands Type-Sensitive Information Principles for Global Correlations
Physical theories with local structure similar to quantum theory can allow beyond-quantum global states that are in agreement with unentangled Gleason’s theorem. In a standard Bell experiment any
Simple conditions constraining the set of quantum correlations
The characterization of the set of quantum correlations in Bell scenarios is a problem of paramount importance for both the foundations of quantum mechanics and quantum information processing in the

TLDR
Considering the space of intrinsically n-partite correlations, the possibility of distilling weak non-local boxes to the algebraically maximal ones without any communication is shown, improving on previously known methods which still required partial communication.
Almost-Quantum Correlations Violate the No-Restriction Hypothesis.
TLDR
It is proved that, contrary to quantum correlations, no generalized probabilistic theory satisfying the no-restriction hypothesis is able to reproduce the set of almost-quantum correlations.
From no-signalling to quantum states
Characterising quantum correlations from physical principles is a central problem in the field of quantum information theory. Entanglement breaks bounds on correlations put by Bell’s theorem, thus
Characterizing and witnessing multipartite correlations : from nonlocality to contextuality
In the past century, experimental discoveries have witnessed phenomena in Nature which challenge our everyday classical intuition. In order to explain these facts, quantum theory was developed, which
Almost-quantum correlations and their refinements in a tripartite Bell scenario
We study the set of almost quantum correlations and their refinements in the simplest tripartite Bell scenario where each party is allowed to perform two dichotomic measurements. In contrast to its
Geometry of the quantum set on no-signaling faces
Since Bell's theorem we know that quantum mechanics is incompatible with local hidden variable models, the phenomenon known as quantum nonlocality. However, in spite of steady progress over years,
Information Causality in the Quantum and Post-Quantum Regime
TLDR
This work simulates correlations that are stronger than allowed by quantum mechanics by exploiting the effect of polarization-dependent loss in a photonic Bell-test experiment and highlights the special importance of anisotropic regions of the no-signalling polytope in the study of fundamental principles.

Quantum correlations require multipartite information principles.
TLDR
This work shows that no principle based on bipartite information concepts is able to singleout the set of quantum correlations for an arbitrary number of parties, and implies that new and intrinsically multipartites information concepts are needed for their full understanding.
Nonlocal correlations as an information-theoretic resource
It is well known that measurements performed on spatially separated entangled quantum systems can give rise to correlations that are nonlocal, in the sense that a Bell inequality is violated. They
Quantum networks reveal quantum nonlocality.
TLDR
This work shows, using its framework, how any one-way entanglement distillable state leads to nonlocal correlations and proves that quantum nonlocality is a non-additive resource, which can be activated.
Bell inequalities with no quantum violation and unextendable product bases.
TLDR
This work associates an intriguing class of bound entangled states, constructed from unextendable product bases with a wide family of tasks, for which quantum correlations do not outperform the classical ones but there exist supraquantum nonsignaling correlations that do provide an advantage.
A convergent hierarchy of semidefinite programs characterizing the set of quantum correlations
TLDR
It is shown that in some cases it is possible to conclude that a given set of correlations is quantum after performing only a finite number of tests, and used in particular to bound the quantum violation of various Bell inequalities.
Information causality as a physical principle
TLDR
It is suggested that information causality—a generalization of the no-signalling condition—might be one of the foundational properties of nature and help to distinguish physical theories from non-physical ones.
Tight Bell inequalities with no quantum violation from qubit unextendible product bases
We investigate the relation between unextendible product bases (UPB) and Bell inequalities found recently in [R. Augusiak et al., Phys. Rev. Lett. 107, 070401 (2011)]. We first review the procedure
Limit on nonlocality in any world in which communication complexity is not trivial.
TLDR
A partial answer to the question why are the correlations achievable by quantum mechanics not maximal among those that preserve causality is given by showing that slightly stronger correlations would result in a world in which communication complexity becomes trivial.
Interconversion of nonlocal correlations
In this paper, we study the correlations that arise when two separated parties perform measurements on systems they hold locally. We restrict ourselves to those correlations with which arbitrarily

TLDR
This work provides a tight constraint inequality imposed by this principle and proves that this principle singles out quantum correlations in scenarios represented by any graph, implying that the exclusivity principle might be one of the fundamental principles of nature.
