Stub?

The article was classified as a stub. However, I am not sure what additional information would be expeceted?

In my opinion, two alternatives would make sense:

Leave the article as it is, maybe with a bit rephrasing, and link it to quantum state for more information;
Merge with quantum state

What would be the preferred option?

This article can definately be expanded as the concept of the expectation value is more diverse than what has been written. You can talk about expectation values and what they mean physically - i.e. observables and non-observables. This article would certainly benefit from a merger with expectation value (quantum mechanics) as they are really the same. I suggest NOT merging with quantum state however, as the quantum state is well, a state or parameter, while the expectation value is an operation on the state.

Merger

User:Frostlion has proposed to merge this article with Expectation value (quantum mechanics). Please add your comments below. --B. Wolterding 10:25, 3 July 2007 (UTC)[reply]

Merge. I agree with the merger, the articles cover the same topic. The concept of "expectation value" is not restricted to quantum mechanics, it is used in all areas of quantum physics (relativistic and non-relativistic). The title of the merged article should be Expectation value (quantum physics). --B. Wolterding 10:25, 3 July 2007 (UTC)[reply]

Merge. Yes please merge these pages. I don't see any real point of difference between the expectation value of quantum physics or quantum mechanics. Renji07 23:50, 13 August 2007 (UTC)[reply]
- If no one else has any objections to this, can the merger be performed within two weeks? Also I suggest that this article be merged into expectation value (quantum mechanics) seeing as its usage is really in the application of quantum mechanics.
  - The proposal has been around for quite a while, so you can just go ahead. (Or I could also do that within the next two weeks.) However, I do not agree with you that the usage of the concept is really in quantum mechanics. The expectation value is used just as well in quantum statistical mechanics and quantum field theory. That's why I said the target article should be Expectation value (quantum physics). --B. Wolterding 08:30, 16 August 2007 (UTC)[reply]
