in the classical way.
NO WAVES.
The Quantum State Propagates like a Wave from each of the slits, spreading out everywhere it can and interfering.
Waves show:
1. Superposition 2. Interference
NO WAVES.
The Quantum State Propagates like a Wave from one of the slits, spreading out everywhere.
Waves show:
2. No interferenceàall spread out.
In this way, the Feynman + Huyghens constructions are mathematically equivalent.
1. In Huyghens, propagation occurs from all points along the wavefront.
2. In Feynman, a quantum state will try to find and explore all possible superpositions of the available states. That is, it will not pick either ‘this one’ or ‘that one’, but it will pick ALL OF THEM simultaneously.
