Quantum mind by physicists, some of which regard the "alive and dead" cat superposition as quite real. Schrödinger's famous thought experiment poses the question, ""when" does a quantum system stop existing as a superposition of states and become one or the other?" In the same way, it is possible to ask whether the brain's act of making a decision is analogous to having a superposition of states of two decision outcomes, so that making a decision means "opening the box" to reduce the brain from a combination of states to one state. But even Schrödinger didn't think this really happened to the
P-adic quantum mechanics wave functions, in which case the problem of the probabilistic interpretation of the "p"-adic valued wave function arises. As there does not exist a suitable "p"-adic Schrödinger equation, path integrals are employed instead. Some one-dimensional systems have been studied by means of the path integral formulation, including the free particle, the particle in a constant field, and the harmonic oscillator. P-adic quantum mechanics p"-adic quantum mechanics is a collection of related research efforts in quantum physics that replace real numbers with "p"-adic numbers. Historically, this research was inspired by the discovery that the Veneziano amplitude of the open bosonic string,
