Schrödinger's cat n. (also Schrödinger cat) an imaginary cat which features in a thought experiment or paradox concerning the quantum-mechanical superposition of states (see note below); (in extended use) any system or entity in which incompatible states are held to coexist until resolved by observation or another event.The cat is imagined as enclosed in a box with a radioactive source and a poison that will be released when the source (unpredictably) emits radiation, the cat being considered (according to quantum mechanics) to be simultaneously both dead and alive until the box is opened and the cat observed. Schrödinger conceived of it as a thought experiment to illustrate (or ridicule) an interpretation of the quantum-mechanical superposition of states (associated with Niels Bohr), according to which the quantum state of a particle could not be known until an observation was made; prior to that it had to be described physically in terms of all possible states.The concept was described by Schrödinger in Naturwissenschaften (1935) 23 812.
