Scientists find way to teleport atoms on optic fibres


Australian boffins find way to teleport atoms
Researcher compares it to Star Trek beaming
Method involves lasers, extremely cold temperatures
AUSTRALIAN physicists have discovered a method that could see atoms being teleported between Sydney and Perth and pave the way for possible Star Trek-like travel in the future.
The method involves cooling down a group of atoms and shooting lasers at them, making them "appear to disappear" before using transporting them along optic fibres at light speed to another location where they can be reconstructed.

The "simple" way of transporting atoms was developed by physicists Murray Olsen, Ashton Bradley, Simon Haine of the Australian Research Council Centre for Quantum-Atom Optics, and and Joseph Hope of ANU.

Dr Olsen told NEWS.com.au the method was very much like the Star Trek characters' favourite way to get back onto the ship.

The atoms are cooled to almost absolute zero, or -273C. At a billionth of a degree above this temperature, a quirk of physics makes all the atoms start behaving in the same way. Then the scientists zap them with two lasers. “If you cool these atoms down enough ... in a condensate, they all enter the same quantum state,” Dr Olsen said.

“When a few thousand atoms are overlapping (and you hit them with the laser beams)… they basically disappear.

“We can use an optic fibre (to transport the signal at the speed of light) into a second condensate, which could be in another room, or another building, or another state.

“We’ve got the coldest thing in the universe and the fastest speed in the universe.”

Could this explain my recent bouts of "transporter psychosis?!" :)

You know what, I think I'll take a shuttle craft thanks.

There's also this comment on the site:

this is great no more waiting 30mins on Pizza deliveryI think I'd rather wait the 30 minutes so my pizza arrives hot.

But I'm sure this could be used fo SOMETHING, perhaps the transportation of dry ice.
