Quantum Teleportation: now at 25 Kilometers

Imagine taking something. Anything. Then take the data that perfectly and with perfect security describes that 'something', and then perfectly reassembles it into another 'something'. When you do it, you do it instantly. And in so doing you do it without that data traveling through time and space. In other words: teleportation.
Scientist at MIT have now done this, teleporting data over a distance of 25 kilometers. While very science fictionish, it was just last year that a government lab revealed it had been operating a Quantum Internet for several years. Why is all of this so important. Just think about your computer. The computation of data meets resistance from the natural properties of distance (even if just microns) and convective resistance of physical matter. Now move that data from there to your router, through a network and it must reassemble again, over and over from multiple points, each with inherent latencies. Just ping a remote server.
Quantum teleportation of data is akin to you and I each pulling a card out of a deck of cards, not looking at our own card, then each of us walking into a different room and as we are turning our own card over to look at, before we even know what our own card is, we each know what card the other holds. It is that fast.
This paves the way towards creating Quantum Networks for instantaneous communcations with space explorers, far flung satellites and remote operations on other worlds. It creates the potential of creating perfect data security as data would not travel. It would just appear. Wow!

Cool stuff. I have a number of friends that work in quantum information. Hope to be around to watch the field for the next 30 years

It's good to see this, most articles usually talk about how far away we are from transporting matter, not what's useful about the level of transportation that appears to be within reach.

Quantum computing has been around (known about) for a while. This is one of the first true applications that could be useful for the general publics use.

Agreed. Why teleport matter when we can teleport data and use that data to reassemble matter that exists elsewhere? Still a ways off, but just in banking and securities, lots of money to be made in security and securities.

Sorta. It isn't like Star Trek's transporter though, you still have to transport particles in a wavelike uncertain state to the destination by normal methods. The information transports instantaneously but the entangled particles do not.
Not only that, but the uncertainty remains behind while you're doing the transportation. This is basically like Kirk saying "I want two security men to beam down to the planet right now!" Five redshirts show up, knowing that only two will survive but they don't know which two. Meanwhile backstage, the Enterprise launches five coffins to the planet via shuttlecraft. They have no idea which two are the lucky winners. It takes, say, 2 hours to land.
2 hours later, the five security men assemble on the transporter pad, awaiting the special effects. Five coffins land on the planet, and the transporter flunky randomly chooses which two get to raise their coffin lids, that's about it.

I swear, sometimes this fricking science shite blows me away.

I'm not sure why this is a story as scientists have already used quantum teleportation over 88 miles back in 2012.

I guess because it's data and not a single photon?

But yeah, it's because it's data and not just a single piece of "info"
