Science Scoops: Beam Me Up, Scotty!

It's true! It's happened! It's amazing! Scientists at the Australian National University have successfully “teleported” a laser beam encoded with data! That's right. Australian physicist Ping Koy Lam and his 12-member team were able to completely break apart a data-filled light beam into billions of photons. Then, after making some measurements of the destroyed beam, they were able to fully reconstruct an exact replica of the destroyed beam a meter (more than a yard) away!

But don't get your hopes too high—yet—that this fantastic development will lead to human teleportation. Right now, Lam's teleport system will be used in a new generation of super-fast computers. But Lam says that he believes the process, called “quantum teleportation” (which takes but a nanosecond, or one billionth of one second), will soon be used for teleporting matter. In fact, he predicts that someone will probably be able to teleport an atom or a group of atoms in the next three to five years!

Teleporting a living person, however, would likely be virtually impossible, Lam says. “In theory, there is nothing stopping us, but the complexity of the problem is so huge that no one is thinking seriously about it at the moment.”
