The term teleportation is a little misleading. Matter is not being transported but, rather, information. Sort of like dissasembling a house brick by brick, and simultaneously destroying the original brick and making a duplicate brick at a location down the street.
My understanding is that it really isn't even that -- they're simply applying a magnetic field to change the spin on a particle and its paired particle automatically spins in the opposite direction. This should happen instantly regardless of the distance they are seperated, which is cool because you should be able to place them millions of miles apart and the change will always be immediate. Interpret spin direction as 1's and 0's and you have a really amazing way to digitally communicate without delays based on the speed of light and it affects a lot more in your life than you think. (Example: the greatest distance you can use a cellphone from a tower is only so many miles. If you are on a boat offshore or in a remote location it can be a big issue. The protocol used has a timeout and that timeout limit is exceeded once you go go too far out because of the time it takes the radio wave to reach the tower and return. Lots of issues in satellite communication, long distance computer communication, etc, could be removed through this.)
Changing the spin on a particle doesn't exactly translate into teleporting a person, or even an object. You'd have to have all of the matter there and arranged properly. Changing the spin on particles in that matter wouldn't do much.
