Long Distance Particle 'Teleportation' Successful

[I'm Murrin]

Neowin.net, 23rd August:

Physicists have carried out successful teleportation with particles of light over a distance of 600m across the River Danube in Austria.

When physicists say "teleportation", they are describing the transfer of key properties from one particle to another without a physical link. Quantum teleportation relies on an aspect of physics known as "entanglement"; whereby the properties of two particles can be tied together even when they are far apart. Einstein called it "spooky action at a distance".

Long distance teleportation is crucial if dreams of superfast quantum computing are to be realised.

"The really interesting question for us was whether we could do this outside a lab setting, in the environment used for today's fibre-optic communications," co-author Rupert Ursin of the University of Vienna told BBC News Online. "This is very important if you are talking about investing money in quantum communication."

Quantum teleportation could be harnessed for fast, powerful computers or communication networks.

Of course the first thing I thought of when I read the title was the Transporter from Star Trek. I suppose we're a still pretty far from being able to teleport to work every day but having ultra high speed data transfer with this breakthrough would be extremely useful. What a world we live in.

Now we just need someone to invent the Heisenberg compensators, and transportation will be an everyday occurence!

but we might have to worry about transporter psycosis

Where's Lt. Barkley when you need him!

[Sheol]

remember its brokley, maybe we cold stick people in there and try and give it to em

[Fist and Faith]

I'm sure the explanation would be waaaaay beyond me, but I'd lovelovelove to know what key properties were transferred, and how they explain it.

May have to do with Quantum Tunneling.

[Fist and Faith]

As if!

[Loredoctor]

As if!

?

[Gadget nee Jemcheeta]

I think "As If!" is an absolutely perfect response

In the News: Teleporting Is Real¹.

¹ For certain definitions of the word "teleport".

I saw something similar to this approach a couple of years ago. Researchers at IBM (or was it Bell Labs? *shrug* do not recall) built an ellipse made of atoms then placed one atom at focal point 1. What happened is that a "ghost image" of the atom appeared at focal point 2 but it reacted in every way as if it were an actual atom.

What a week, though! First non-Newtonian thrust and now teleportation. The only thing we are missing is faster-than-light communication but we can probably get that via entanglement.

If we can "teleport" photons we can pass information via it.

Hell, I saw something similar to this right in the OP of this thread (2004)!

Seriously, how is this any different from the news 11 years ago?

As to your final point, entanglement won't allow for f-t-l communication, IIRC.

I don't know. I am not the one who resurrected the thread.

It was a question for everyone. Maybe I should have said, "Does anyone see how ... blah, blah,"
