…. To prove the resulting entanglement, the spin orientation of both electrons was read out and compared. Although the spin orientation of each electron individually was completely random, exactly as predicted by quantum mechanics, the researchers found that the two orientations were always exactly opposite to each other. This proves that the two electrons are entangled and behave as a single entity. 'Incidentally, the three-metre distance between the electrons was chosen quite arbitrarily. We could conduct this experiment over much larger distances', Hanson adds.
This seems to be another proves for quantum entanglement which based on simple algebra of Bell concept, anyway in quantum mechanics system, mathematic involved is more complicate vector concept! Here we could show that actually it based on Einstein hidden variable…
Quantum mechanics is one of the most important theories in modern physics, despite of their predictability and accuracy; it is facing with crucial philosophic problems. Indeed the problems could be solved, and the theory could be improved by using "Vacuum Mechanics" - from "vacuum mechanics link
