Phys. Rev. Lett. 87, 010403 (2001) [4 pages]“All versus Nothing” Inseparability for Two ObserversReceived 23 January 2001; published 18 June 2001 A recent proof of Bell’s theorem without inequalities [A. Cabello, Phys. Rev. Lett. 86, 1911 (2001)] is formulated as a Greenberger-Horne-Zeilinger–type proof involving just two observers. On one hand, this new approach allows us to derive an experimentally testable Bell inequality which is violated by quantum mechanics. On the other hand, it leads to a new state-independent proof of the Kochen-Specker theorem and provides a wider perspective on the relations between the major proofs of no hidden variables. © 2001 The American Physical Society URL:
