    Inequality
In summary, there is strong evidence that the Leggett-Garg inequality is violated in quantum mechanics, which leads to the rejection of many realist interpretations. However, the Bohm interpretation, which is a hidden variable theory, is not included in this category. It is suggested that this interpretation may make the same experimental predictions as nonrelativistic quantum mechanics.

There's considerable evidence that the Leggett-Garg inequality is violated in QM: http://physicsworld.com/cws/article/news/27640
the experimenters claim that this rules out a large class of realist interpretations.
Nonetheless, the Bohm interpretation--a hidden, realist hidden variable theory--is not part of this category, correct?
If it's simply a reformation of the mathematics of QM, I would think that it would make exactly the same experimental predictions.

Correct.

Yes, at least for nonrelativistic QM.
 

FAQ: Does the Bohm interp. rely on the Leggett-Garg inequality?

What is the Bohm interpretation?

The Bohm interpretation, also known as the pilot-wave theory, is a deterministic interpretation of quantum mechanics that suggests particles have definite positions and trajectories, as opposed to the probabilistic nature of the Copenhagen interpretation.

What is the Leggett-Garg inequality?

The Leggett-Garg inequality is a mathematical inequality that tests the compatibility between classical physics and quantum mechanics. It states that if a system satisfies a set of assumptions known as macrorealism, it must also satisfy the inequality.

How does the Bohm interpretation relate to the Leggett-Garg inequality?

The Bohm interpretation relies on the Leggett-Garg inequality to test the validity of macrorealism in quantum systems. If the inequality is violated, it suggests that the system cannot be described by classical physics and supports the probabilistic nature of quantum mechanics.

What is the significance of the Leggett-Garg inequality in the Bohm interpretation?

The Leggett-Garg inequality is significant in the Bohm interpretation because it provides a way to experimentally test the deterministic nature of the theory. If the inequality is violated, it would suggest that the Bohm interpretation is not a complete description of quantum mechanics.

Are there any experiments that have tested the Leggett-Garg inequality in the context of the Bohm interpretation?

Yes, there have been several experiments that have tested the Leggett-Garg inequality in the context of the Bohm interpretation. These experiments have shown that the inequality is violated, providing evidence against the deterministic nature of the Bohm interpretation.
