Bell's theorem witnesses that the predictions of quantum theory cannot be reproduced by theories of local hidden variables in which observers can choose their measurements independently of the source. Working out an idea of Branciard, Rosset, Gisin and Pironio, we consider scenarios which feature several sources, but no choice of measurement for the observers. Every Bell scenario can be mapped into such a correlation scenario, and Bell's theorem then discards those local hidden variable…

Beyond Bell’s Theorem II: Scenarios with Arbitrary Causal Structure
It is found that it is possible to talk about classical correlations, quantum correlations and other kinds of correlations on any directed acyclic graph, and this captures various extensions of Bell scenarios that have been considered in the literature.
Experimental test of quantum causal influences
Since Bell’s theorem, it is known that local realism fails to explain quantum phenomena. Bell inequality violations manifestly show the incompatibility of quantum theory with classical notions of
Experimental violation of local causality in a quantum network
This work investigates a quantum network consisting of three spatially separated nodes whose correlations are mediated by two distinct sources, and experimentally witness the emergence of the so-called non-bilocal correlations by violating a Bell-like inequality under the fair-sampling assumption.
Quantifying Causal Influences in the Presence of a Quantum Common Cause.
It is shown that every pure bipartite entangled state violates the classical bounds on causal influence, thus, answering in negative to the posed question and opening a new venue to explore the role of causality within quantum theory.
Unifying framework for relaxations of the causal assumptions in Bell's theorem.
A conceptual and computational framework for treating quantum mechanical correlations, which employs the language of Bayesian networks to systematically construct alternative causal structures and bound the degree of relaxation using quantitative measures that originate from the mathematical theory of causality.
Experimental test of nonlocal causality
The results demonstrate the incompatibility of quantum mechanics with a broad class of nonlocal causal models, which includes Bell-local models as a special case, and allows outcome dependence: a direct causal influence between the outcomes of measurements of remote parties.

This work provides a new, general, and conceptually clear method for the derivation of polynomial Bell inequalities in a wide class of scenarios, and shows how the construction can be used to allow for relaxations of causal constraints and naturally gives rise to a notion of nonsignaling in generalized Bell networks.
Quantum violations in the Instrumental scenario and their relations to the Bell scenario
This work identifies the simplest causal structure which exhibits a separation between classical, quantum, and post-quantum correlations and derives inequalities for this scenario and shows that they are closely related to well-known Bell inequalities.
Quantum common causes and quantum causal models
Reichenbach’s principle asserts that if two observed variables are found to be correlated, then there should be a causal explanation of these correlations. Furthermore, if the explanation is in terms
Causal structures from entropic information: geometry and novel scenarios
This paper treats Bell scenarios involving multiple parties and multiple observables per party, and exhibits inequalities for scenarios with extra conditional independence assumptions, as well as a limited amount of shared randomness between the parties.


Bell’s theorem without inequalities
It is demonstrated that the premisses of the Einstein–Podolsky–Rosen paper are inconsistent when applied to quantum systems consisting of at least three particles. The demonstration reveals that the

For mixed states, correlations arising from a single ideal measurement on each system may obey standard Bell inequalities, yet when each system is subjected to a sequence of ideal measurements the correlations are nonlocal.
Information processing in generalized probabilistic theories
A framework in which a variety of probabilistic theories can be defined, including classical and quantum theories, and many others, is introduced, and a tensor product rule for combining separate systems can be derived.
On the Einstein-Podolsky-Rosen paradox
THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional
How much measurement independence is needed to demonstrate nonlocality?
A connection is demonstrated between models that weaken the assumption that measurement settings are freely chosen by the observers, allowing partial correlation, and models that allow classical communication between the distant parties, including models that exploit the detection loophole.

A simple measure of the degree of measurement independent is defined for correlation models, and it is shown that all spin correlations of a singlet state can be modeled via giving up just 14% of measurement independence.
A classification of hidden-variable properties
Hidden variables are extra components added to try to banish counterintuitive features of quantum mechanics. We start with a quantum-mechanical model and describe various properties that can be asked
Proposed Experiment to Test Local Hidden Variable Theories.
A theorem of Bell, proving that certain predictions of quantum mechanics are inconsistent with the entire family of local hidden-variable theories, is generalized so as to apply to realizable
On the free-will postulate in Quantum Mechanics
The so-called "free will axiom" is an essential ingredient in many discussions concerning hidden variables in quantum mechanics. In this paper we argue that "free will" can be defined in different
Random numbers certified by Bell’s theorem
It is shown that the non-local correlations of entangled quantum particles can be used to certify the presence of genuine randomness, and it is thereby possible to design a cryptographically secure random number generator that does not require any assumption about the internal working of the device.
