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 variables relate to quantum entanglement?

Hidden variables could potentially provide a deterministic explanation for quantum entanglement, suggesting that particles are connected through these unseen factors.

Are there any experiments that support hidden variable theories?

Yes, experiments like the Bell test experiments have been conducted to test the predictions of hidden variable theories against standard quantum mechanics.

What is the significance of Bell's theorem in this context?

Bell's theorem shows that no local hidden variable theory can reproduce all the predictions of quantum mechanics, challenging the idea of hidden variables.

Can hidden variable theories be reconciled with quantum mechanics?

Some interpretations, like de Broglie-Bohm theory, attempt to reconcile hidden variables with quantum mechanics, but they remain controversial.
