Phys. Rev. Lett. 74, 831–834 (1995)Limits to Quantum Mechanics as a Source of Magic Tricks: Retrodiction and the Bell-Kochen-Specker TheoremReceived 15 September 1994; published in the issue dated 6 February 1995 A trick discovered by Vaidman, Aharanov, and Albert permitting retrodiction of the outcomes of more measurements than one would naively have thought possible is extended to a case in which the retrodicted observables are forbidden all to have values by a Bell-Kochen-Specker theorem. A rather peculiar analysis shows that an even better trick that retrodicts the outcomes of more informative measurements of these same observables is impossible. © 1995 The American Physical Society URL:
