An experiment is suggested that is capable of distinguishing between the de Broglie-Bohm theory and standard quantum mechanics.

We discuss a number of comments on quant-ph/9801061, and propose to introduce the concept of ’Causal Indistinguishability’. The incompatibility between Quantum Mechanics and Nonlocal Causality appears to be unavoidable: upholding of Quantum Mechanics by experiment would mean to live with influences backward in time, just as we are now living with such faster than light.

Many beautiful experiments have been addressed to test standard quantum mechanics against local realistic models. Even if a strong evidence favouring standard quantum mechanics is emerged, a conclusive experiment is still lacking, because of low detection ef-ficiencies. Recently, experiments based on pseudoscalar mesons have been proposed as a way for obtaining a conclusive experiment. In this ...

Elaborating on a previous work by Simon et al. [Phys. Rev. Lett. 85, 1783 (2000)] we propose a realizable quantum optical single-photon experiment using standard present day technology, capable of discriminating maximally between the predictions of quantum mechanics (QM) and noncontextual hidden variable theories (NCHV). Quantum mechanics predicts a gross violation (up to a factor of 2) of the ...

Contextuality, the impossibility of assigning a single random variable to represent the outcomes of the same measurement procedure under different experimental conditions, is a central aspect of quantum mechanics. Thus defined, it appears in well-known cases in quantum mechanics, such as the double-slit experiment, the Bell-EPR experiment, and the Kochen-Specker theorem. Here we examine context...

In this investigation, we have suggested a special two-slit experiment which can distinguish between standard and Bohmian quantum mechanics, even at the statistical level. At the first step, we have shown that observable individual predictions at suitable time intervals, obtained from these theories, are inconsistent. But, at the statistical level, they are consistent as was expected. Then, usi...
