While there's nothing to say that quantum entanglement can't happen with macroscopic objects, before now it was thought that the effects weren't noticeable at larger scales – or perhaps that the macroscopic scale was governed by another set of rules. This new research suggests that's not the case. In fact, the same quantum rules apply here, too, and can actually be seen as well. Researchers vibrated the tiny drum membranes using microwave photons and kept them kept in a synchronized state in terms of their position and velocities. Both the first and the second study have been published in Science.
