You know...quantum teleportation of a photon a few feet between each other?

Yea? Well, we're up to ten miles now.

I told you it was coming! Now they just have to increase the size that they can teleport.

Well, not necessarily building ourselves for human transport just yet...but in terms of data getting from place to place instantly, that would definitely be a nice thing to have.

Beats having to wait for a file to download.

Physics owns


science owns.

I'd imagine we're at most a century or so away from being able to teleport living beins. Not necessarily humans, but...

Score another one for science!




The key here, however, is that what's being transported is quantum information. The particles themselves aren't magically transported, just the state they're in. We probably won't see matter teleportation any time soon, but the article points out the most obvious benefit of this: quantum data transfer for computers. Lag would be a thing of the past.

Awesome... eventually we might not have to worry about downloading a file for like 16 hours in extreme cases... =P

This technology should be really useful in the long run...

Lag AND download time.

Think...downloading a Wii/Gamecube ROM in an instant! Woo!

How fast is this teleportation, exactly? Speed of light or so?

Teleporting humans would be awesome, but it's a long way off, and that's if it's even possible to begin with.

From the articles I've read, it's actually... faster than the speed of light. As in, instantaneous. It's almost magical.

Wow

If that's true, it could definitely help us explore space and colonize other planets, if humanity ever decides to do so Communication throughout the solar system would be instantaneous, and if we teleport larger objects, we could send supplies to the new colonies instantly.

To quote the terminology, tachient speed. Objects already traveling at the speed of light or faster (multiples of light, in essence). I remember reading up on that a LONG while back since it apparently went with Einstein's theory because it never went into things already traveling at said speed (since if it went to the speed of light, its mass would become infinite).

To build off what Kles has there, at the point where we can teleport beings, we'd likely be steps away from cloning those beings as well. All that would have to be done is take down the data that passes through from one end to another and simply repeat it.

Of course, that assumes we ever pursue that sort of matter reconstruction "teleportation." From what I've heard, scientists right now are considering that sort of method as very impractical. The power required and the chance of error would make it too dangerous and inefficient.

Hum, this fixes that issue people feared about that if we had Mars bases, communications between there and Earth would be waaay too slow.

Not anymore!

Yeah, I instantly thought of the communication uses between earth and ships or probes in space. Rather than the hours or days of delay we have now, it'd be instantaneous. Would it also be able to go through matter? A problem before would be lack of communication when stuff goes behind another planet, but this would eliminate that if so.

Considering the experiment spanned 10 miles, I'm pretty sure there was a good deal of matter in the way. So basically, yes.


The question we'd all like to know is just what are the limits of this. Could it transmit data halfway across the world? Could it transmit data from Earth to Mars? Could it transmit data from Earth to Pluto? That will be the exciting part.

Pretty sure they've theorized that it's possible to do something like that, which would essentially put radio out of business.

You know, instant shots of planets from far away? Hey, you want to see what Jupiter looks like in real-time?

Etc. etc.

I could see this ushering in a new age of privacy in communication; after all, if it can skip over matter, it can avoid any "middle man" who may be listening.

Exciting!
