What is the purpose of this article?
[edit](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
[edit]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
[edit]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)
Merge to superposition principle?
[edit]There's nothing particularly unique about a "quantum" superposition. It's still just a superposition. Though I suppose making it a redirect to "addition" doesn't have the same ring to it ;) – Closed Limelike Curves (talk) 02:49, 31 August 2024 (UTC)
- While I agree that this article should make the point that superposition is not uniquely quantum (given a suitable reference), I don't agree that this article should merge. Superposition of material waves are directly viewable but superposition of probability is invisible and can only be inferred by consequences. That is why it took so long to sort out QM.

Section on quantum computing deleted
[edit]I reverted a new section on quantum computing. It had three problems. First it was incorrect: per the authoritative source
- Nielsen, M. A., & Chuang, I. L. (2010). Quantum Computation and Quantum Information: 10th Anniversary Edition. Cambridge: Cambridge University Press, page xix
superposition is not required for quantum computation. Second it did not give sources for important definitions like "uniform superpositions". Third it was overly detailed on issues unrelated to the topic: it was about issues important for quantum computation, not superposition. Johnjbarton (talk) 15:57, 7 September 2024 (UTC)
