Beam Me Up Scotty

Some of the science fiction from shows like "Star Trek" is becoming less fiction and more science as apparent by the latest breakthrough in teleportation from the Joint Quantum Institute at the University of Maryland.
Now the JQI team, along with colleagues at the University of Michigan, has succeeded in teleporting a quantum state directly from one atom to another over a meter. That capability is necessary for workable quantum information systems because they will require memory storage at both the sending and receiving ends of the transmission.

In the Jan. 23 issue of the journal Science, the scientists report that, by using their protocol, atom-to-atom teleported information can be recovered with perfect accuracy about 90 percent of the time — and that figure can be improved.

"Our system has the potential to form the basis for a large-scale 'quantum repeater' that can network quantum memories over vast distances," Monroe said. "Moreover, our methods can be used in conjunction with quantum bit operations to create a key component needed for quantum computation."

Now my science knowledge, not great to begin with, make most of the meat of the article a bit difficult to comprehend but 2 things I did get from the story. One is with 90% accuracy I wouldn't want to be transported as it stands now and secondly, science is well on it's way to Star Trek type technology breakthroughs. How cool is that?
