Schrödinger's cat Schrödinger's cat Schrödinger's cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The scenario presents a cat that may be simultaneously both alive and dead, a state known as a quantum superposition, as a result of being linked to a random subatomic event that may or may not occur. The thought experiment is also often featured in theoretical discussions of the interpretations of quantum mechanics. Schrödinger coined the term "Verschränkung" (entanglement) in
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,
