Has Superposition Been Proven?

Summary: The quantum superposition principle has been tested on a scale as never before in a new study. ... By confirming this phenomenon -- "the heart of quantum mechanics," in Richard Feynman's words -- on a new mass scale, improved constraints on alternative theories to quantum mechanics have been placed.

Is superposition proven?

The phenomenon, known as a superposition, plays a significant role in quantum mechanics, but has proven extremely challenging to decipher. While experiments may be able to induce a superposition, scientists are yet unable to actually measure it; doing so causes the superposition to 'collapse.

Who proved superposition?

According to Léon Brillouin, the principle of superposition was first stated by Daniel Bernoulli in 1753: "The general motion of a vibrating system is given by a superposition of its proper vibrations." The principle was rejected by Leonhard Euler and then by Joseph Lagrange.
