Pilot wave theory and quantum tunneling

[johnob]

Just a question about pilot wave theory as an alternative to SQM. Researchers in ANU have recently shown that quantum tunnelling of a particle through a barrier is instantaneous. Does this finding verify the Copenhagen superposition interpretation of QM and at the same time invalidate the deterministic pilot wave theory.

You'll have to provide more of a citation than that - there's no way any of us can say anything sensible about a piece of research that we haven't yet seen. Where is the peer-reviewed publication of this result?

I'm not the starter of this discussion although I found the publication.

Apologies for the omission. That is the publication I'm referring to.

Copenhagen interpretation and pilot wave theory have the same measurable predictions. If the experiment is compatible with the former, then it is also compatible with the latter.

There have been claims in the literature that pilot wave theory makes different predictions for the tunneling time. But such claims are misleading, as explained e.g. in
