In this article, a broad class of theories called "objective local theories" are defined, motivation for considering these theories is given, and experimental consequences of the class are investigated.Abstract:
A broad class of theories, called "objective local theories," is defined, motivation for considering these theories is given, and experimental consequences of the class are investigated. An extension of previous analyses by Bell and by Clauser et al. shows that predictions of objective local theories and of quantum mechanics differ, and that an experimental test of the entire family of objective local theories can be performed. The experimental requirements are given. Objective local theories satisfying a plausible but experimentally untestable supplementary assumption are shown to be incompatible with existing experimental data.read more

Bell's theorem. Experimental tests and implications
John F. Clauser,Abner Shimony +1 more
TL;DR: Bell's theorem represents a significant advance in understanding the conceptual foundations of quantum mechanics as mentioned in this paper, showing that essentially all local theories of natural phenomena that are formulated within the framework of realism may be tested using a single experimental arrangement.

TL;DR: 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.

TL;DR: In this paper, the authors present a loophole-free violation of local realism using entangled photon pairs, ensuring that all relevant events in their Bell test are spacelike separated by placing the parties far enough apart and by using fast random number generators and high-speed polarization measurements.

TL;DR: A review of the progress in photonic quantum information processing can be found in this article, where the emphasis is given to the creation of photonic entanglement of various forms, tests of the completeness of quantum mechanics (in particular, violations of local realism), quantum information protocols for quantum communication, and quantum computation with linear optics.
