Superposition Sprinzip (IMAGE) University of Vienna Caption This is the superposition of orders of quantum measurements. Applying the superposition principle to a photon's motion can lead it in two different directions at the same time. If a different order of operations is applied in each path, this can be used to create a genuinely indefinite order of operations.
