A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism1, in which the properties of the physical world are independent of our observation of them and no signal travels faster than light. A Bell test requires spatially distributed entanglement, fast and high-efficiency detection and unpredictable measurement settings2,3. Although technology can satisfy the first two of these requirements4–7, the use of physical devices to… Expand
Experimental measurement-dependent local Bell test with human free will
A Bell test can rule out local realistic models, and has potential applications in communications and information tasks. For example, a Bell inequality violation can certify the presence of intrinsicExpand
A Kantian Solution for the Freedom of Choice Loophole in Bell Experiments
Bell's theorem is based on three assumptions: realism, locality, and measurement independence. The third assumption is identified by Bell as linked to the freedom of choice hypothesis. He holds thatExpand
Analysis of Assumptions in BIG Bell Test Experiments
TLDR
It is concluded that further tests of local realism need better setup calibration to avoid apparent signaling or necessity of the complicated underlying quantum model. Expand
On Superdeterministic Rejections of Settings Independence
Relying on some auxiliary assumptions, usually considered mild, Bell's theorem proves that no local theory can reproduce all the predictions of quantum mechanics. In this work, we introduce a fullyExpand
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 actionsExpand
Relaxed Bell Inequalities with Arbitrary Measurement Dependence for Each Observer
Bell's inequality was originally derived under the assumption that experimenters are free to select detector settings independently of any local "hidden variables" that might affect the outcomes ofExpand
A Statistical Approach to Two-particle Bell Tests
  • Xianming Meng
  • 2021
Extensive experimental tests of the Bell inequality have been conducted over time and the test results are viewed as a testimony to quantum mechanics. In considering the close tie between quantumExpand
Time , Entropy , and Entanglement contextually defined
The prevailing interpretations of physics are based on deeply entrenched assumptions, rooted in classical mechanics. Logical implications include: the denial of entropy as a fundamental physicalExpand
Simulation of the Bell inequality violation based on quantum steering concept
TLDR
By use of a model of polarizers that obeys the Malus’ law and quantum steering concept, i.e. superluminal influence of the states of entangled pairs to each other, simulation of phenomena is presented and the result completely agrees with prediction of quantum mechanics. Expand
Contingent Free Choice: On Extending Quantum Theory to a Contextual, Deterministic Theory With Improved Predictive Power
TLDR
It is suggested that quantum experiments, such as the EPR experiment, involving measurements across positions in spacetime, can be recast as a game with imperfect information between human agents and the universe. Expand

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 ofExpand
Violation of local realism with freedom of choice
TLDR
This paper presents an experiment that violates Bell’s inequality while simultaneously closing the locality loophole and addressing the freedom-of-choice loophole, also closing the latter within a reasonable set of assumptions. Expand
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.

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. Expand
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. Expand
Random numbers certified by Bell’s theorem
TLDR
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.

Comment on "Cosmic Bell Test: Measurement Settings from Milky Way Stars"
This Comment argues that two assumptions, which are presented as basic assumptions of Bell's theorem in [J. Handsteiner et al., Phys. Rev. Lett. 118, 060401 (2017)] and elsewhere, in fact follow fromExpand
Relaxed Bell inequalities and Kochen-Specker theorems
The combination of various physically plausible properties, such as no signaling, determinism, and experimental free will, is known to be incompatible with quantum correlations. Hence, theseExpand
