Elementary particles part ways with their properties

“Spooky action at a distance,” Einstein’s summation of quantum physics, has been a criticism of quantum mechanics since the field emerged. So far, descriptions of entangled particles to explain their apparently faster-than-light responses, and even explanations for the phase shifts induced by an electromagnetic field in regions where it is zero—the “Aharonov-Bohm” effect—have mostly addressed these concerns. However, recent theoretical and…
