| − | The principle of '''superposition''' states that should two waves occupy the same space, their [[amplitude|amplitudes]] will add together. In [[quantum mechanics]], the principles refers to the wave equation of a system being able to [[decoherence|decohere]] to multiple states, and implies that a particle or system exists in multiple states at the same time. | + | The principle of '''superposition''' states that should two waves occupy the same space, their [[amplitude]]s will add together.
