Sorry, Einstein. Quantum Study Suggests ‘Spooky Action’ Is Real.

Sorry, Einstein. Quantum Study Suggests ‘Spooky Action’ Is Real.: John Markoff:

The Delft researchers were able to entangle two electrons separated by a distance of 1.3 kilometers, slightly less than a mile, and then share information between them. Physicists use the term “entanglement” to refer to pairs of particles that are generated in such a way that they cannot be described independently. The scientists placed two diamonds on opposite sides of the Delft University campus, 1.3 kilometers apart.

Each diamond contained a tiny trap for single electrons, which have a magnetic property called a “spin.” Pulses of microwave and laser energy are then used to entangle and measure the “spin” of the electrons.

The distance — with detectors set on opposite sides of the campus — ensured that information could not be exchanged by conventional means within the time it takes to do the measurement.

‘Spooky’, . Not sure which is crazier here: that Einstein may have been wrong, that quantum entanglement is likely a real phenomenon, or that they’ve concocted a way to test all of this.
