The paper is open access and published in Nature Communications.Abstract said:Decades ago, Aharonov and Bohm showed that electrons are affected by electromagnetic potentials in the absence of forces due to fields. Zeilinger’s theorem describes this absence of classical force in quantum terms as the “dispersionless” nature of the Aharonov-Bohm effect. Shelankov predicted the presence of a quantum “force” for the same Aharonov-Bohm physical system as elucidated by Berry. Here, we report an experiment designed to test Shelankov’s prediction and we provide a theoretical analysis that is intended to elucidate the relation between Shelankov’s prediction and Zeilinger’s theorem. The experiment consists of the Aharonov-Bohm physical system; free electrons pass a magnetized nanorod and far-field electron diffraction is observed. The diffraction pattern is asymmetric confirming one of Shelankov’s predictions and giving indirect experimental evidence for the presence of a quantum “force”. Our theoretical analysis shows that Zeilinger’s theorem and Shelankov’s result are both special cases of one theorem.
Non-local quantum force is a type of force that acts between particles that are not in direct physical contact with each other. This force is predicted by quantum mechanics and is responsible for the phenomenon of quantum entanglement.
Unlike other types of forces, such as gravity or electromagnetism, non-local quantum force does not require particles to be in close proximity to each other in order to act. It can act instantaneously over large distances, which is why it is often referred to as "spooky action at a distance."
One of the most famous experiments that provided evidence for non-local quantum forces is the Bell test experiment. This experiment showed that entangled particles can exhibit correlations that cannot be explained by classical physics, providing strong evidence for the existence of non-local quantum forces.
Scientists study non-local quantum forces through a variety of experiments, including the Bell test experiment, as well as other experiments that measure the behavior of entangled particles. These experiments often involve creating entangled particles and then observing how they behave when they are separated by large distances.
The existence of non-local quantum forces has significant implications for our understanding of the universe and the fundamental laws of physics. It challenges our traditional notions of causality and locality, and has the potential to revolutionize fields such as quantum computing and communication.
