“Alive and Dead?”

Schrödinger’s Cat, Quantum Superposition, and the Measurement Problem 1. A Thought-Experiment with Nine Lives In 1935, Austrian physicist Erwin Schrödinger devised a theatrical setup to spotlight how bizarre quantum rules look when scaled up to everyday objects[ 1 ]. A sealed steel box contains: a single radioactive atom with a 50 % chance to decay in one hour, a Geiger counter wired to a hammer, a vial of lethal cyanide, an unsuspecting cat. If the atom decays, the counter trips, the hammer smashes the vial, and the cat dies; if not, the cat survives. Quantum mechanics says the atom is in a superposition of “decayed” and “not-decayed,” so—by entanglement—the whole apparatus, cat included, must be in a superposition of ‘alive’ and ‘dead’ until an observer opens the box[ 1 ][ 2 ]. Schrödinger wasn’t condemning tabbies; he was mocking the idea that microscopic indeterminacy automatically balloons into macroscopic absurdity. 2. Superposition 101 The principle: if a quantum syste...
