That sounds very nice. But you can not teleport matter to a point of the space if in the destination point, there is not matter. I want to say that you can not create matter from nothing. A transport must exist.

There's several levels of non-living objects to test this on too. I'd imagine transporting somebody's laptop while it's running would be a big hurdle, for example.

**Warning: weird ramblings**
From what I've read, it's not nearly as simple as "send info on X - destroy X - create copy Y from info".
To my understanding they are transporting quantum states uninterrupted, an important distinction from "ordinary" copying.
Whether this will transport the original consciousness uninterrupted as well, I can't tell. Hell, I can't even form an opinion here, except through intuition, which is a pretty useless tool in physics once you go to QM.
A good test would be to see if this thing could create duplicates, but even then both could be the true you, but immediately become "different" because of existing in different places. Ie . you'd only be the same thing as long as you were completely identical.
As a final question, how would teleporting differ from traveling in time from position A to position B?
In teleporting, would you die any more than you die while passing through time?

Well, you're gambling your life every night then.
From your conscience point of view, what makes you sure you are 'the same'?
The question is what are you? If you define yourself as the continuity of your consciousness, then teleportation is safer than sleep. Or do you feel like you must be the same in a spatial continuity through time (probably like your position can be derived along time and any dimension of space at any point)? If so, you can indeed never teleport. However, space continuity is a macroscopic thing. I am pretty sure your wave function would be continuous in space and time, and, from a quantum point of view, your position is a consequence of your wave function, so that point probably doesn't hold.
Now my quantum mechanics courses are err... 10 year old, so I may just have been telling utter bullshit.

The moment I read of Stefu's concern, that quote about going to asleep and waking as a different person came to my mind.
Because, really, how can I tell that it is *I* who went to sleep last night? Maybe I'm just a replica that has the exact memories of the old me.
Therefore, the only problem with teleportation is the fact that people are aware of the fact that their old self will be destroyed.
If we could trick people into believing that it is actually their very matter that is transported, and that there remains no former self that is destroyed, then no-one would care except the people who built the bloody thing.
Problem solved, everyone would be happy, except that those builders might be somewhat reluctant to use the device.
But, then again, I myself would never dare using such a thing.
