That question assumes that Schrödinger's paradox is possible, and that someone can be both dead and alive at the same time.
So, is that actually true in Halacha? Can a person (or anything else) have a status of being both dead and alive at the same time?
What kind of effects would it have if someone was in a dual life state?
Could he count for a minyan? Would it be tumat meit?
I know that the cat is actually reductio ad absurdum, but seems to be taken quite seriously by some people (i have seen it in Stephen Hawking's books, for example).
