Local Realism and Conditional Probability
Emilio Santos has argued (Santos, Studies in History and Philosophy of Physics http://arxiv-org/abs/quant-ph/0410193) that to date, no experiment has provided a loophole-free refutation of Bell’s inequalities. He believes that this provides strong evidence for the principle of local realism, and argues that we should reject this principle only if we have extremely strong evidence. However, rece...
متن کاملGeneralized measurements and local realism
The structure of a local hidden variable model for experiments involving sequences of measurements is analyzed. Constraints imposed by local realism on the conditional probabilities of the outcomes of such measurement schemes are derived. Therefore, we claim that the so-called “hidden” nonlocality leads directly to a violation of the premisses of local realism. This claim is further supported b...
متن کاملQuantum codewords contradict local realism
Quantum codewords are highly entangled combinations of two-state systems. The standard assumptions of local realism lead to logical contradictions similar to those found by Bell, Kochen and Specker, Greenberger, Horne and Zeilinger, and Mermin. The new contradictions have some noteworthy features that did not appear in the older ones. PACS: 03.65.Bz, 89.80.+h, 89.70.+c ∗Permanent address: Depar...
متن کاملLocal realism of macroscopic correlations.
We identify conditions under which correlations resulting from quantum measurements performed on macroscopic systems (systems composed of a number of particles of the order of the Avogadro number) can be described by local realism. We argue that the emergence of local realism at the macroscopic level is caused by an interplay between the monogamous nature of quantum correlations and the fact th...
متن کاملGeneralized quantum measurements and local realism
The structure of a local hidden variable model for experiments involving sequences of measurements is analyzed. Constraints imposed by local realism on the conditional probabilities of the outcomes of such measurement schemes are explicitly derived. The violation of local realism in the case of “hidden nonlocality” is illustrated by an operational example. Typeset using REVTEX 1
