Grössing's deterministic subquantum model

[ajw]

The last few day's I have become more intrigued by the work of the Austrian Gerhard Grössing and his team. They have developed a classic sub quantum model, based on the macroscopic 'walkers' experiments from Ives Clouder (http://challengingbell.blogspot.com/2013/02/qm-reflection.html).
They are able to simulate different double slit experiments. In https://arxiv.org/ftp/arxiv/papers/1004/1004.4596.pdf they give an ontological explanation for the wave function 'collapse' and hint to the explanation for the Heisenberg uncertainty principle.

So far I haven't found many discussion about their work on the web. As with Joy Christian's theory, one of the implications would be that quantum computing is not possible (although I haven't found them saying this). What is your opinion?

Good post, Albert Jan.

I did see a popular article about this work, but don't have a link for it.

I would not be too sympathetic to the idea of a "wave function collapse", but otherwise their work seems quite interesting, since they are doing actual experiments.

Although I have not thought about their work, let alone investigated it in detail, my suspicion is that their model is probably non-local, like de Broglie-Bohm theory.

I don't believe it is possible to provide a purely local account of what is observed by them without invoking something like what I have proposed in my work.

As for quantum computers, they are doomed in any case, because my work already proves that quantum entanglement is not a fundamental feature of the world.

Best,

Joy

The model in the article mentioned doesn't address EPR type scenario's. It is strongly based on the Clouder experiments, so non-locality doesn't seem to be an issue here. Like with the 'walker' droplets, a particle is seen to interact with the surrounding energy field, thereby creating self induced waves (resembling, but a bit different then those in de Broglie-Bohm theory).

About the measurement (and thus the so called collapse of the wave function) they say

The actual measurement process can thus be understood as a process of symmetry breaking, ultimately resulting in energy/momentum transfer from the particle to the detecting apparatus.
