As a result, Schrödinger's cat has had enduring appeal in popular culture. The experiment is not intended to be actually performed on a cat, but rather as an easily understandable illustration of the behavior of atoms. The scenario is often featured in theoretical discussions of the interpretations of quantum mechanics, particularly in situations involving the measurement problem. Though originally a critique on the Copenhagen interpretation, Schrödinger's seemingly paradoxical thought experiment became part of the foundation of quantum mechanics. This poses the question of when exactly quantum superposition ends and reality resolves into one possibility or the other. Yet, when one looks in the box, one sees the cat either alive or dead, not both alive and dead. The Copenhagen interpretation implies that, after a while, the cat is simultaneously alive and dead.
a single atom decaying), the flask is shattered, releasing the poison, which kills the cat. a Geiger counter) detects radioactivity (i.e. In Schrödinger's original formulation, a cat, a flask of poison, and a radioactive source are placed in a sealed box. This thought experiment was devised by physicist Erwin Schrödinger in 1935 in a discussion with Albert Einstein to illustrate what Schrödinger saw as the problems of the Copenhagen interpretation of quantum mechanics. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead, while it is unobserved in a closed box, as a result of its fate being linked to a random subatomic event that may or may not occur. In quantum mechanics, Schrödinger's cat is a thought experiment that illustrates a paradox of quantum superposition. As illustrated, the objects are in a state of superposition: the cat is both alive and dead.
