Experiment can decide between standard and Bohmian quantum mechanics

TL;DR

This paper compares standard and Bohmian quantum mechanics through thought experiments involving entangled and unentangled particles, revealing differences at both individual and statistical levels under certain conditions.

Contribution

It introduces two thought experiments that highlight conditions where standard and Bohmian quantum mechanics predictions diverge, especially with selective detection.

Findings

Different predictions at the individual level in the first experiment.

Breakdown of statistical equivalence with selective detection in the second.

Objections to the experimental results are discussed.

Abstract

In this investigation, we have considered two thought experiments to make a comparison between predictions of the standard and the Bohmian quantum mechanics. Concerning this, a two-particle system has been studied at two various situations of the entangled and the unentangled states. In the first experiment, the two theories can predict different results at the individual level, while their statistical results are the same. In the other experiment, not only they are in disagreement at the individual level, but their equivalence at the statistical level also breaks down, if one uses selective detection. Furthermore, we discuss about some objections that can be raised against the results of the two suggested experiments.
