Measurement and entanglement both have a “spooky” nonlocal flavor to them. Now physicists are harnessing that nonlocality to probe the spread of quantum information and control it. The post Physicists Discover ‘Unobservable’ Phase Transition in Quantum Entanglement first appeared on Quanta Magazine
In 1935, Albert Einstein and Erwin Schrödinger, two of the most prominent physicists of the day, got into a dispute over the nature of reality. Einstein had done the math and knew that the universe must be local, meaning that no event in one location could instantly affect a distant location. But Schrödinger had done his own math, and he knew that at the heart of quantum mechanics lay a strange…
