New adventures with Schrödinger's cat: The role of statistical uncertainty in stabilizing measurement

Abstract

We reopen Erwin Schrödinger's thought experiment involving a cat in an informationally impenetrable box. A common view is that the cat enters a superposition of alive/ dead because of a lack of observation, leading to uncertainty about the state of the cat. We, on the other hand, argue that the cat only enters a superposition if everything about the cat is known prior to the box being closed. The superposition results from a lack of uncertainty inside the box. Rather than interpreting this state of affairs as a live and dead cat interacting with each other, we suggest that the more natural interpretation is that of an inability to precisely position events within spacetime due to the lack of uncertainty. We clarify how stable measurement depends on a diversified portfolio of statistical uncertainty, and how the lack of such uncertainty in Schrödinger's box precludes stabilization. V
