2 v 3 4 J un 1 99 6 Branching Space - time analysis of the GHZ theorem ∗

Abstract

Greenberger, Horne, Shimony and Zeilinger gave a new version of the Bell theorem without using inequalities (probabilities). Mermin summarized it concisely; but Bohm and Hiley criticized Mermin’s proof from contextualists’ point of view. Using the Branching Space-time language, in this paper a proof will be given that is free of these difficulties. At the same time we will also clarify the limits of the validity of the theorem when it is taken as a proof that quantum mechanics is not compatible with a deterministic world nor with a world that permits correlated space-related events without a common cause. 1 Greenberger, Horne, Shimony, Zeilinger and Mermin Greenberger, Horne, Shimony and Zeilinger (1990) developed a proof of the Bell theorem without using inequalities. Following Mermin, one can To be published in Foundations of Physics 1996. E-mail: belnap+@pitt.edu Supported by OTKA Foundation, No: T -015606 and T-017176 E-mail: leszabo@ludens.elte.hu
