What are hidden variables in quantum mechanics?

What are hidden variables in quantum mechanics?

Hidden variables are theoretical constructs that aim to explain the randomness in quantum mechanics by suggesting that there are underlying factors not accounted for in standard quantum theory.

How do hidden variable theories differ from standard quantum mechanics?

Standard quantum mechanics relies on probabilistic outcomes, while hidden variable theories propose that these outcomes are determined by unobservable factors.

Can you give an example of a hidden variable theory?

One well-known hidden variable theory is the de Broglie-Bohm theory, which introduces 'pilot waves' guiding particles along deterministic paths.

Are there any experiments that support hidden variable theories?

Yes, experiments like those testing Bell's theorem have been conducted, but they generally support standard quantum mechanics over hidden variable theories.

What are the implications of hidden variable theories for quantum mechanics?

If hidden variable theories were proven true, it could imply that quantum mechanics is incomplete and that there are deeper layers of reality.
