What is the 'Schrödinger's cat' thought experiment?
Schrödinger's cat is a quantum-mechanical thought experiment, devised by Austrian physicist Erwin Schrödinger, which presents a scenario in which a cat can be simultaneously both dead and alive. Schrödinger stated, a cat sealed in a box with poison exists in superimposed dead and alive states until one looks into the box, which forces the dual states into a single outcome.
