http://www.physorg.com/news/2011-12-quantum-world-diamonds.html This is the first time, apparently, they've demonstrated quantum entanglement in relatively macroscopic matter. In this case it's small diamonds, and at room temperature. Seems to me at the end of this, it should be possible to do without EM waves and cables in phones, televisions, internet service, etc. What are the limits here? Is the implication that all diamonds are entangled?
