We observe strong violation of Bell's inequality in an Einstein-Podolsky-Rosen-type experiment with independent observers. Our experiment definitely implements the ideas behind the well-known work by Aspect et al. We for the first time fully enforce the condition of locality, a central assumption in the derivation of Bell's theorem. The necessary spacelike separation of the observations is achieved by sufficient physical distance between the measurement stations, by ultrafast and random setting…

Loophole-free Bell's experiments and two-photon all-versus-nothing violations of local realism
We introduce an extended version of a previous all-versus-nothing proof of impossibility of Einstein-Podolsky-Rosen's local elements of reality for two photons entangled both in polarization and path
Significant-Loophole-Free Test of Bell's Theorem with Entangled Photons.
TLDR
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.
On the experimental violation of Mermin's inequality with imperfect measurements
TLDR
It is found that experimental violation is well accessible for spins larger than 1, for quantum efficiencies compatible with the current state of the art.
Violation of a Bell-like inequality in single-neutron interferometry
TLDR
This work measures correlations between two degrees of freedom (comprising spatial and spin components) of single neutrons; this removes the need for a source of entangled neutron pairs, which would present a considerable technical challenge.
The ultimate loophole in Bell’s theorem: The inequality is identically satisfied by data sets composed of ±1′s assuming merely that they exist
Abstract Bell’s stated assumptions in deriving his inequality were sufficient conditions. It is shown that a far simpler condition exists for derivation of the inequality: the mere existence of
Bell’s Inequality Violation on MATLAB
Bell’s inequality provides a framework to objectively decide the locality of a system. In this article, we demonstrate the violation of Bell’s inequality on IBM quantum devices and Matlab. Our main
Towards a Loophole-Free Bell's Inequality Experiment
A violation of Bell’s inequality suggests an incompatibility of quantum mechanics with local realistic theory. An experimental violation of the Clauser-Horne-Shimony-Holt (CHSH) variant of the Bell’s
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),
Testing Bell's inequality with cosmic photons: closing the setting-independence loophole.
TLDR
By setting the detectors using pairs of quasars or patches of the cosmic microwave background, observed violations of Bell's inequality would require any such coordination to have existed for billions of years-an improvement of 20 orders of magnitude.
