Editing Schrödinger's cat (section)

== Analysis ==
In modern terms Schrodinger's hypothetical cat experiment describes the [[measurement problem]]: quantum theory describes the cat system as a combination of two possible outcomes but only one outcome is ever observed.<ref name="PeresCat">{{Cite journal |last=Peres |first=Asher |date=January 1988 |title=Schrödinger's immortal cat |url=http://link.springer.com/10.1007/BF01882873 |journal=Foundations of Physics |language=en |volume=18 |issue=1 |pages=57–76 |doi=10.1007/BF01882873 |bibcode=1988FoPh...18...57P |issn=0015-9018}}</ref>{{rp|57|q=Nobody has ever seen a cat in such a strange

The experiment poses the question, "''when'' does a quantum system stop existing as a superposition of states and become one or the other?"  (More technically, when does the actual quantum state stop being a non-trivial [[linear combination]] of states, each of which resembles different classical states, and instead begin to have a unique classical description?) Standard microscopic quantum mechanics describes multiple possible outcomes of experiments but only one outcome is observed. The thought experiment illustrates this apparent paradox. Our intuition says that the cat cannot be in more than one state simultaneously—yet the quantum mechanical description of the thought experiment requires such a condition.
