Superposition Explained
What superposition actually claims, and the wording to avoid.
Superposition
What is superposition?
Superposition is a quantum state formed by combining other states, each carrying an amplitude.
Superposition is not ordinary ignorance about a hidden value, and it is not an object being in two places at once.
Its observable signature is interference: amplitudes that can cancel as well as add.
