Before people start jumping up and down hoping that we'll soon be able to tell someone to 'beam them up, and don't forget the clothes this time', there's two things you need to consider:

1. Most importantly, it was 'beaming' of the state of an atom, not of the atom itself. This isn't moving matter from place A to place B, but transferring a property of matter from place A to place B---which already has the same matter available. Two very different things.

2. It has succeeded with one atom, which is indeed an important step. But our bodies contain about 4 kmol atoms, that is, 24 * 10^27 of the buggers. Even storing the quantum state of one fingertip is completely beyond us.

In other words: great science, but don't expect to be able to beam yourself from place to place in before you die.
Some people say that cats are sneaky, evil and cruel. True, and they have many other fine qualities as well.

obviously, this tecnhology is still in its embryonic stages, but it could get to the foetus stage soon. Remember that scientific and technological advancement seems to follow an exponential curve quite a bit of the time.

I'm sure Microsoft will have a Release Candidate out soon! :-P

The report struck me as being a step towards something more akin to the "affinity" technology used in Peter F. Hamiltons various stories rather than a teleportation system. For those unfamiliar to his novels, "affinity" is a form of telepathy based on specially designed neural cells that are cloned and contain a signalling mechanism based on quantum entanglement - each cell in pair of cloned neurons is aware of the state of of the other via the phenomenon.

[or something like that ;-)]

And who in their right mind would trust their body to a Microsoft powered teleporter ?

Also, once a month you'd have to go through a defrag teleportation to correctly put your most used extremities back in place :-D

I'm not saying that this experiment brings us any closer to Star Trek style teleportation - I don't know enough to comment - but teleportation *is* most commonly used to mean not transferring the actual atoms, but instead transferring the information and rebuilding elsewhere where the matter is already available. So the way you describe them, they are the same sort of thing.

The important part here is not that you can transmit information, but that you can transmit it instantaneously - faster than light. Theoretically you could communicate to somewhere in the Andromeda galaxy this way, in an instant.

Which means we've broken the "information faster than the speed of light" barrier.

I'd like to see them set up an actual transmitter/reciever based on this stuff, just so they can repeat "Come here watson, I want you."

A couple of things have been floating in my head after hearing about this..
 1. What happens to the original atom?
 If this experiment could be scaled up to scan an living thing,would the original still be OK, or would it have been affected/altered by the scanning?

 2. As well as its potential use as a teleport, couldn`t it be used as a duplicator?

I think the whole 'matter cannot be made or destroyed' principle gets rid of the idea that you can simply make something blink out of existence then back in again.  It has to go somewhere and back again.
