Abstract All experimental tests of the violation of Bell's inequality suffer from some loopholes. We show that the locality loophole is not independent of the detection loophole: in experiments using low efficient detectors, the locality loophole can be closed equivalently using active or passive switches.

Detection-loophole-free test of quantum nonlocality, and applications.
TLDR
A source of entangled photons is presented that violates a Bell inequality free of the "fair-sampling" assumption, and is used to generate "device-independent" private quantum random numbers at rates over 4 orders of magnitude beyond previous experiments.
The necessity of randomness in tests of Bell inequalities
The possibility that detectors may affect the input quantum entangled state is pointed out. It is suggested that experiments testing Bell inequalities should be repeated with more randomly oriented
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
Stronger tests of the collapse-locality loophole in Bell experiments
Several versions of quantum theory assume some form of localized collapse. If measurement outcomes are indeed defined by localized collapses, then a loophole-free demonstration of Bell non-locality
Optical tests of quantum nonlocality: from EPR-Bell tests towards experiments with moving observers
Past, present and future experimental tests of quantum nonlocality are discussed. Consequences of assuming that the state-vector collapse is a real physical phenomenon in space-time are developed.
The various versions of Bell's inequality: an alternative proof
By considering uncommon factors as spacetime events that influence the spin orientations in the EPRB thought experiment, it is intended to show that one can still introduce the correlation functions.
Quantum Nonlocality with Arbitrary Limited Detection Efficiency.
TLDR
It is proved that quantum theory predicts the violation of one of these inequalities for all η(min)>0.1 so that nonlocality can be demonstrated with arbitrarily small limited detection efficiencies.
Loophole-free Bell test with one atom and less than one photon on average
We consider the entanglement between two internal states of a single atom and two photon number states describing either the vacuum or a single photon and thus containing, on average, less than one
Experimental violation of a Bell's inequality with efficient detection
TLDR
Here, correlations in the classical properties of massive entangled particles (9Be+ ions): these correlations violate a form of Bell's inequality, and the high detection efficiency of the apparatus eliminates the so-called ‘detection’ loophole.
Bell's inequality without alternative settings
A suitable generalized measurement described by a 4-element positive operator-valued measure (POVM) on each particle of a two-qubit system in the singlet state is, from the point of view of Einstein,

TLDR
A proposal for an experimental realization of Bohm s spin-2 particle version of the Einstein-Podolsky-Rosen experiment is described, which will not only close the detector efficiency loophole, but in addition will permit enforcement of the locality condition.
