: Weren't they doing this with photons a year or so ago?
Yep. The big news is they're doing it with particles large enough to consider "matter" now.
The big problem I see with applying this to human transportation is the same big problem that there always was with the idea of a transporter. Even "old-style", ripping matter apart and beaming it somewhere and sticking it back together isn't the hard part - I imagine indistinct hunks of a single element, or somet mixture that you don't care if it gets mixed up further, could possibly be done that way some day. The hard part is recording the exact pattern of the original particles and putting them back together the right way. The same problem applies to quantum teleportation - how are you going to perfectly map every atom of a person to the right "blank" atom at the destination, so the right parts of you teleport back the right way and you don't end up scrambled? (On that note, how exactly is the entanglement done, physically? Could it be done to a particle in the middle of a bunch of others without ripping them all apart first anyway).
When it comes down to it the problem is ultimately an informational one, not a physical one. Before we can do any of this, or something like replication (a closely related technology), we need atomic (or subatomic) level fully 3D scanners, such that you could record the position of every particle, including it's exact position and velocity, and it's a physical impossibility to know both at once... so basically it can't be done. I'm much more interested in personal wormholes or FTL systems, allowing one to move in distorted time or space... could make for some fun bullet-time moves, too :-)
