In the analysis of experiments designed to reveal violation of Bell-type inequalities, it is usually assumed that any hidden variables associated with the nth particle pair would be independent of measurement choices and outcomes for the first (n - 1) pairs. Models which violate this assumption exploit what we call the memory loophole. We focus on the strongest type of violation, which uses the two-sided memory loophole, in which the hidden variables for pair n can depend on the previous… 
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres
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.
Computational perspectives on Bell Inequalities and many-body quantum correlations
The predictions of quantum mechanics cannot be resolved with a completely classical view of the world. In particular, the statistics of space-like separated measurements on entangled quantum systems
A Rigorous Test of Bell’s Inequality and Quantum Teleportation Employing Single Atoms
In 1935, Einstein, Podolsky, and Rosen pointed at contradictions between quantum mechanics and classical theories which obey the principles of realism (physical properties exist without observation)
Event-Ready Bell Test Using Entangled Atoms Simultaneously Closing Detection and Locality Loopholes.
A statistically significant, event-ready Bell test based on combining heralded entanglement of atoms separated by 398 m with fast and efficient measurements of the atomic spin states closing essential loopholes to refute the hypothesis of local realism with a significance level P<2.57×10^{-9}.
Significant-Loophole-Free Test of Bell's Theorem with Entangled Photons.
A Bell test is reported that closes the most significant of loopholes that provide loopholes for a local realist explanation of quantum mechanics, using a well-optimized source of entangled photons, rapid setting generation, and highly efficient superconducting detectors.
A significant-loophole-free test of Bell's theorem with entangled photons
John Bell’s theorem of 1964 states that local elements of physical reality, existing independent of measurement, are inconsistent with the predictions of quantum mechanics (Bell, J. S. (1964),
Leggett-Garg Inequalities Draft : 26 October 2018
In contrast to the spatial Bell’s inequalities which probe entanglement between spatially-separated systems, the Leggett-Garg inequalities test the correlations of a single system measured at
Loophole-free Bell test using electron spins in diamond: second experiment and additional analysis
It is found that the winning probability per trial in the CHSH game can be bounded knowing only the mean of the RNG bias, which implies that the experimental result is robust for any model underlying the estimated average Rng bias.
Leggett-Garg Inequalities
In contrast to the spatial Bell's inequalities, which probe entanglement between spatially-separated systems, the Leggett-Garg inequalities test the correlations of a single system measured at
Loopholes in Bell inequality tests of local realism
Bell inequalities are intended to show that local realist theories cannot describe the world. A local realist theory is one where physical properties are defined prior to and independent of
