The subject of Einstein-PodolskyRosen correlations—those strong quantum correlations that seem to imply "spooky actions at a distance"—has just been given a new and beautiful twist. Daniel Greenberger, Michael Home and Anton Zeilinger have found a clever and powerful extension of the two-particle EPR experiment to gedanken decays that produce more than two particles. In the GHZ experiment the spookiness assumes an even more vivid form than it acquired in John Bell's celebrated analysis of the… Expand
A Neglected Route to Realism about Quantum Mechanics
Bell's Theorem assumes that hidden variables are not influenced by future measurement settings. The assumption has sometimes been questioned, but the suggestion has been thought outlandish, even byExpand
Locality in the Everett Interpretation of Heisenberg-Picture Quantum Mechanics
Bell's theorem depends crucially on counterfactual reasoning, and is mistakenly interpreted as ruling out a local explanation for the correlations which can be observed between the results ofExpand
Bell's Questions Resolved Via Local Realistic Quantum Mechanics
‘... all this action at a distance business will pass [like the ether]. If we're lucky it will be to some big new development like the theory of relativity. Maybe someone will just point out that weExpand
Bell’s theorem without inequalities: on the inception and scope of the GHZ theorem
Since its inception, fifty years ago, Bell’s theorem has had a long history not only of experimental tests but also of theoretical developments. Studying pairs of correlated quantum-mechanicalExpand
Locality and Counterfactual Reasoning in the Everett Interpretation of Heisenberg-Picture Quantum Mechanics

The conceptual problem of nonlocality is replaced with a conceptual problems of proliferating labels, as correlated systems and observers undergo measurement-type interactions with newly-encountered objects and instruments; it is suggested that this problem may be resolved by considering quantum field theory rather than the quantum mechanics of particles.

Einstein-Podolsky-Rosen Correlations, Entanglement and Quantum Cryptography
The Einstein, Podolsky and Rosen [1] (EPR) argument was presented in 1935 as an attempt to show that quantum mechanics is incomplete. EPR defined as a starting point the premises of “reality” and “noExpand
Clear Local Realism Advances Bell's Ideas, Demystifies QM, Etc.
Negating the classical/quantum divide in line with Bell's hidden-variable ideas, we resolve Bell's ‘action-at-a-distance' dilemma in accord with his hopes. We identify the resultant theory as clearExpand
Bell's Theorem Refuted; Commonsense Local Realism Defined
An open letter to Bellians and the Annals of Physics' Editors re -- it's a proven scientific fact: a violation of local realism has been demonstrated theoretically and experimentally -- after AoPExpand
Radical Nonlocality
This article points out a nonlocality of quantum mechanics that is significantly more radical than that implied by violations of Bell locality or Einstein locality. It consists in the fact that theExpand
Greenberger-Horne-Zeilinger (GHZ) theorem asserts that there is a set of mutually commuting nonlocal observables with a common eigenstate on which those observables assume values that refute theExpand

Generalization of the Greenberger-Horne-Zeilinger algebraic proof of nonlocality
We further develop a recent new proof (by Greenberger, Horne, and Zeilinger—GHZ) that local deterministic hidden-variable theories are inconsistent with certain strict correlations predicted byExpand
