Putting a Human in Superposition I recognize the practical aspects of this would be absurd, but I must admit the premise of what it would take to put a human in a superposition of states is an amusing thought exercise and has some relevance towards me understanding actually in what scenarios QM is applicable and particularly a bit on the bride between classical and quantum. And surely this must be theoretical contrive-able, since we presume QM is the underlying framework of classical systems as well. So what would it take to put a whole human system in superposition of states? My intuition imagines an individual in a self-contained suit in the middle of a supervoid (or some similar isolation, maybe even throw the human in a Faraday cage) in space. Would this be sufficient assuming all mater and light so sparsely distributed as for there to be periods in which the human interacts with no external bodies? Or is there something fundamentally wrong with my understanding, and in what scenario could the entire human be in superposition (if possible)? Note that I'm resisting any questioning as to what said human would experience which might be a tad more debatable and philosophical.
