It is widely known that there are at least a dozen different interpretations of quantum theory. One of them is the de Broglie – Bohm interpretation. In this formulation, a quantum potential appears that guides quantum particles in their movements. The shape of the quantum potential makes each particle move along its path. However, the existence of only four interactions has been experimentally established. These are electromagnetic, gravitational, weak and strong interactions. That is why it was so important to understand exactly how the quantum potential interacts with particles. The recently obtained result provides evidence of the electromagnetic nature of the quantum potential. The paper in which the electromagnetic nature of the quantum potential was revealed, can be obtained here: Article in the journal, or ArXiv.
