Here is a thought experiment. Imagine Schrodinger's cat... in the traditional model, there is a single observer outside the box, and the observer creates an entanglement with the catbox device which reveals the quantum superposition of the enclosed cat. The cat is said to be in a superposition of both alive and dead. My question is.... is that superposition absolute? or only relative to the observer? What if the box were instead a room. And in the room was another "local" observer of the cat? To the observer outside the room, both the cat and the local observer are in a superposition of alive and dead. However, the local observer would necessarily be either alive or dead only. Thus, the local observer would not see the cat as a superposition of both alive and dead, but as a definite state of one or the other. Supposing the local observer is alive along with the cat, the local observer would say the cat is alive, while the external observer would say that both the cat and the local observer are in a superposition of both alive and dead. I believe this suggests that the observed quantum states are not absolute, but instead, relative to the observer.
