Talk:Quantum superposition

Experiments

Maybe we could eliminate the whole section Experiments and applications. Of course these are some examples, but isn't any QM experiment a demonstration of quantum superposition? All QM experiments are under the assumption they follow somehow Schrodinger equation or some version of Dirac-von Neumann axioms. I agree we could leave some examples but not as experimental evidence and only if it is argued why is a good example of Q superposition, like the slit and the qubit in the lead. --MaoGo (talk) 16:38, 14 May 2018 (UTC)

I partially agree. Some of the experiments on that list are interesting because they involve relatively large systems (like buckyballs or flu viruses), and it's interesting to check that such large systems can be put in coherent superpositions (of position eigenstates, for instance) and can demonstrate interference. I think it's a good idea to keep some discussion of that somewhere in the article. But much of what's there in that section is fluff. Waleswatcher (talk) 17:19, 14 May 2018 (UTC)

We might just move the list to pages like mesoscopic physics or quantum interference, they are maybe not suited here. --MaoGo (talk) 14:36, 15 May 2018 (UTC)

What is the purpose of this article?

(a) to enable professionals to show off their specialized knowledge of the subject and thereby inflate their egos? Or (b) to educate non-professional readers about the subject using language and terms that the average person can understand? 2600:8801:BE1C:1D00:FA07:6031:AB4E:440C (talk) 18:06, 8 August 2024 (UTC)

I guess (c), to explain a complex topic typically taught in 3rd year college physics classes as well as unpaid volunteer editors are able to do. Johnjbarton (talk) 18:45, 8 August 2024 (UTC)

Hamiltonian Evolution of General States

I deleted the entire section "Hamiltonian Evolution of General States". The section did not primarily discuss superposition and had one ref unrelated to the article title. Johnjbarton (talk) 16:28, 28 August 2024 (UTC)

Physical interpretation

I deleted the entire section "Physical interpretation" since it had no sources and it was puzzling mix of topics.

The concept of superposition is fundamental to explain many physical effects. I believe that is what the section was going for, but by way of an example. But the topic is quite involved and needs development.

Similarly the "meaning" or interpretation of superposition itself is involved. The section should summarize the role of superposition in various interpretations of QM esp. Everett and Feynman. Johnjbarton (talk) 16:41, 28 August 2024 (UTC)
