BBCnews is carrying this article detailing a new experiement in "quantum teleportation". For the first time, scientists were able to use the effect to transmit information across a great distance in "real-world" conditions. Go read the article. If it doesn't make your head hurt, you're not paying attention.
This is "the next big thing" folks. When it was first proven you could transmit information using this technique Scientific American editorialized that computers would "experience a signficant discontinuity in peformance increase", which is geek speak for "they'll go from being fast to being really f-ing fast". Should such systems become a reality (so far nothing says they can't), it will almost certainly be possible to have the computing power of one of those CGI "render farms" stuffed into something the size of an iPod. With room to spare.

"...they'll go from being fast to being really f-ing fast..."
Not to mention that all this worry about RF interference between wireless devices could become exceedingly moot.
They're moving on this stuff a lot faster than I was led to believe, which is a good thing unless you're someone who works for the NSA...
Well, I wouldn't say that interference won't be a problem. To the best of my knowledge, no one has tried this on the scale of current cell phone usage or something like that. However, if it's true that entanglement will only affect the specific qubits that are entangled, then interference becomes moot and communications, computing, TV, Radio, etc., all get revolutionized in the technological blink of an eye...
That's what I was referring to. Hey, my SF-loving ass can hope, right?
Does anyone know if there is any sort of theoretical distance limit to this effect? As far as I understand it (translation: no damn clue) there isn't, in which case another Star Trek device (subspace communications, i.e. faster-than-light) might actually be possible. Now if only we could get FTL travel to work...
Steve - maybe I'm missing the point here, but would you want to get to work that fast? If you could, your boss could call you at any time and expect you to be there in minutes (figuring that you'd need to finish what you were doing and walk to your personal teleporter...) - making you just that much more accessible during your private life...
And I don't believe there's a theoritical limit to the distance, however, from my understanding of entanglement, you have to have the paired qubits at each end, meaning they'd need to be paired initially and then moved to the end point for any of this to work.
"... they'd need to be paired initially and then moved to the end point for any of this to work."
Also how I understand it. And no, I wouldn't want to use a teleporter; to paraphrase Douglas Adams: "if you have to take me apart to get me there, then I don't want to go."
