Quantum Entanglement At the Macroscopic Level?


Boing Boing has an article that will roast a few brain cells. Macroscopic Quantum Entanglement. That's right Macroscopic - big enough to be seen by the naked eye. Quantum always meant sub-atomic particle physics to me but here we are, demonstrable entanglement of something you can hold in your hands.

This effect was demonstrated on a pair of diamond crystals, large enough to be seen by the naked eye! In this case, the crystals were 3 millimeters wide and were placed 15 centimeters apart. From the article:
  • A vibration in the crystals could not be meaningfully assigned to one or other of them: both crystals were simultaneously vibrating and not vibrating.

  • Einstein called this phenomenon "spooky action at a distance," and scientists still don't understand how it's possible.

This effect is usually only observed in quantum particles and only at ultra cold conditions, never with objects large enough to be seen. Plus it it not a universally accepted phenomenon either.
