This would violate unitarity.
- kgwgk 6y agoMaybe in the parent comment C is an state (like A) but neither B nor D are states but stand for something undefined to make some kind of analogy. It’s extremely misleading at best.
- wizzwizz4 6y agoNone of them are supposed to be states; I used the word wrong. I meant “particle X is here, particle Y is there”, not the actual quantum state (which would be a superposition). I'm not sure what the correct term for this is.
