This is an important step in future secure communications since it is believed this form of communications cannot be unknowingly tapped.
Teleportation across Calgary marks 'major step' toward creation of 'quantum internet'?REAL OR NOT?
This is a pretty good introduction to quantum computing, a subject which I’ve read about numerous times but constantly find I have to refresh my knowledge of. An ongoing series of four (so far) hype-free articles by someone who seems to know what he’s talking about.

Another effort to explain quantum entanglement in the following video: Quantum Entanglement and the Great Bohr-Einstein Debate.
This is also in response to Network performance concerns.
As I understand it now: quantum entanglement can be used for secure key generation, but not for information transport faster then light. Because there is no control over which entangled info (polarisation or spin e.g. used for the crypto key) will be measured. There is only the knowledge that the other side will get the same ‘key’ with a similar measurement. More info concerning this: see part 09:35-10:23 of the linked movie.
