Vibrating ions get entangled
Quantum entanglement of mechanical vibrations brings 'quantum computing' another step nearer.
The line between the quantum realm and the world of classical mechanics we inhabit has just got a little bit blurrier. Physicists have shown that mechanical vibrations can be entangled, which promises to help along attempts to build quantum computers.

Maybe I missed a point, but isn't this just synchronizing two distant vibrational systems? "Testing that the spins were once again correlated" after transferring synchronized motion in the beryllium ions demonstrates correlation. How did they demonstrate that "manipulating the properties of one immediately affects its entangled partner, no matter how far apart they are" which makes the difference between correlation and entanglement?
?????????many of these words are too difficult to me!
