> "When we think about quantum entanglement, we think about small things," Si said. "We don't associate it with macroscopic objects. But at a quantum critical point, things are so collective that we have this chance to see the effects of entanglement, even in a metallic film that contains billions of billions of quantum mechanical objects." Maybe the mistake is us thinking there is a "quantum level". Rather, quantum mechanical effects are actually real and not just math. Einstein argued this all those years ago, but lost the argument to Neils Bohr at the time (not on the merits of the argument, but by the politics of scientific establishment). John Bell and others have showed the merit in Einstein's viewpoint.
