A local and deterministic model of quantum correlations is always possible, as shown explicitly by Brans in 1988: one simply needs the physical systems being measured to have a suitable statistical correlation with the physical systems performing the measurement, via some common cause. Hence, to derive no-go results such as Bell inequalities, an assumption of measurement independence is crucial. It is a surprisingly strong assumption—less than 1 / 15 bits of prior correlation suffice for a… 
Relaxed Bell inequalities with arbitrary measurement dependence for each observer
TLDR
Modified Bell inequalities are derived that relax measurement independence, for either or both observers, while remaining locally causal, and it is argued that, contrary to various claims in the literature, relaxing freedom of choice need not imply superdeterminism.

TLDR
A simple probabilistic model is constructed allowing the existence of strong correlations between outcomes of distant measurements to be explained in a locally causal way and why the introduction of setting-dependent parameters does not restrict experimenters' freedom of choice.
Rethinking Superdeterminism
Quantum mechanics has irked physicists ever since its conception more than 100 years ago. While some of the misgivings, such as it being unintuitive, are merely aesthetic, quantum mechanics has one
Cosmic Bell Test: Measurement Settings from Milky Way Stars.
TLDR
In tests with polarization-entangled photons, measurement settings were chosen using real-time observations of Milky Way stars while simultaneously ensuring locality, pushing back by ∼600  years the most recent time by which any local-realist influences could have engineered the observed Bell violation.
The relativistic causality versus no-signaling paradigm for multi-party correlations
TLDR
It is shown that, in the multipartite setting, the no-signalling condition is in general stronger than demanding relativistic causality in multi-party correlations, i.e., the rule that correlations do not allow casual loops.
Analysis of the superdeterministic Invariant-set theory in a hidden-variable setting
A recent proposal for a superdeterministic account of quantum mechanics, named Invariant-set theory, appears to bring ideas from several diverse fields like chaos theory, number theory and dynamical
Can Einstein with Bohr Debate on Quantum Mechanics Be Closed
Three experimental groups succeeded recently to close, at the same time, locality and fair sampling loopholes and confirmed that realism understood as counterfactual definiteness may not be used to
Bell Correlations and the Common Future
Reichenbach’s principle states that in a causal structure, correlations of classical information can stem from a common cause in the common past or a direct influence from one of the events in
Tackling Loopholes in Experimental Tests of Bell's Inequality
Bell's inequality sets a strict threshold for how strongly correlated the outcomes of measurements on two or more particles can be, if the outcomes of each measurement are independent of actions

TLDR
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.
Arbitrarily small amount of measurement independence is sufficient to manifest quantum nonlocality.
TLDR
It is proved that even in the simplest Bell test-one involving 2 parties each performing 2 binary-outcome measurements-an arbitrarily small amount of measurement independence is sufficient to manifest quantum nonlocality.
Quantum non-locality—it ainʼt necessarily so...
Bellʼs theorem is 50 years old. There still remains a controversy about its implications. Much of this controversy has its roots in confusion regarding the premises from which the theorem can be
Demonstration of Quantum Nonlocality in the Presence of Measurement Dependence.
TLDR
It is shown that the measurement independence assumption can be widely relaxed while still demonstrating quantum nonlocality, excluding a much larger range of measurement dependent local models than would be possible with an adapted Clauser-Horne-Shimony-Holt (CHSH) inequality.

TLDR
Lower bounds on the min-entropy of the source used to choose the inputs required to deduce any quantum or nonlocal behavior from a Bell inequality violation are found.

Limited measurement dependence in multiple runs of a Bell test
TLDR
It is proved that there remain Bell violations for a sufficiently high, yet non-maximal degree of free will which cannot be simulated by a classical attack, regardless of how many runs of the experiment those choices are correlated over.
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres
TLDR
The data imply statistically significant rejection of the local-realist null hypothesis and could be used for testing less-conventional theories, and for implementing device-independent quantum-secure communication and randomness certification.
