Teleporting QuBits
Jeremy Faludi, 18 Jun 04

Scientists in both the US and Austria have actually teleported matter, not just photons, for the first time.

But hold your horses, this doesn't mean you'll be able to teleport to Fiji anytime soon, if ever--when they say "teleport" they mean transferring the quantum state of one atom to another pre-existing atom. However, this does mean the potential of insanely fast quantum computers: not only would they be able to calculate in parallel by virtue of using QuBits, they wouldn't have to use wires to get data from one part of a chip to another. Though it's a complicated, involved enough process that it would only be used here and there, not to replace every wire. (probably.) And the earlier breakthrough of photon teleportation already meant the possibility of instantaneous-communication networks.

Nature has both the papers from the scientific teams, if you're a paying subscriber, but the BBC has an article you don't have to pay to read, with a helpful diagram showing how the process works (reproduced here.)

The New York Times also had an article about this yesterday:
Scientists Teleport Not Kirk, but an Atom

Some editor at the Times exhibited much less self-control than you, Jeremy, in making the obvious allusion!

EAaaarrrggghhhh!

A transporter accident has duplicated Emily!

The question is, which one is *E*V*I*L*?

I guess only time will tell.

It'll be the one with the "van dyke" beard... it always is.
