Schild’s Ladder


The applet below allows you to perform three simulated experiments, which show how quantum behaviour is hidden when a system becomes entangled, but can be recovered by observations on the complete system. (These are not realistic experiments, but they serve as simple illustrations of the basic idea. Real experiments have been performed to verify these principles, mostly using photons.)
