Part of the Nanotechnology glossary: Superposition is a principle of quantum theory that describes a challenging concept about the nature and behavior of matter and forces at the sub-atomic level.ach photon moves simultaneously in a superposition of possible trajectories, and, furthermore, measurement of the trajectory causes the superposition of states to collapse to a single position. See a video explanation of quantum theory. See a video explanation of Schrodinger's cat.
