patchouli has it right - he's given a MUCH better explanation of quantum entanglement than the dumb article does. And he did it very succinctly.
The upshot is, it doesn`t matter how far apart the entangled particles are, the quantum state gets "broadcast" from one particle to the other instantaneously. One particle could be in a different galaxy on the other side of the universe and you could transmit the data instantly. It`s amazing stuff.

I love the idea of entanglement because firstly it breaks huge numbers of our current physical laws as we view them, and secondly because it introduces the idea of instant communication between any points in the universe which beats the crap out of radio.

This is not teleportation. This is closer to radio than it is teleportation. Basically (VERY basically), there are two particles. Neither choose a charge (negative or positive) until one of them does. If the first particle becomes positive then the second will become negative and visa versa. The cool thing is, they can be miles apart (one could be on Earth and the other could be on the moon, for example) and it would still work. This then becomes a very fast way to transmit a state (negative or positive) over a far distance. If you assign a zero to one state and a one to the other, you get information being transfered.
Also, with teleportation, you would need to destroy yourself and have a perfect clone of you made on the other side. You would die but another you would go on. So I don't see teleporting - a la Star Trek - as being all that popular.
