I'm banging my head against the desk while reading TFA. Sorry, no, it's not "teleportation". Matter is not being moved from one place to another, and no information is being exchanged because a reading on one end means nothing except "Hey, we got the same reading over here, isn't that cool?"

One thing you may be missing here is that the information is destroyed at the source as moves to the target. Also, the quantum state does not have to traverse the space between the source and the target.

The thing that you are saying sounds more like taking a quantum state and making a perfectly correlated duplicate of it. That is less involved process.

At home I use a cheap Asus router loaded with dd-wrt, which is really just Linux. Works great. When the internet is out I reboot it but usually the problem is with the cable provider.

At work it's Ubuntu Linux on the router/firewall. That needs rebooting basically never.

What nonsense. There will never be quantum routers. Measurement will break the quantum entanglement, so the best case scenario is one-time-use single-bit transmission per entanglement previously created... and even then, you'd have to transmit information the old fashioned way to even interpret what was measured.

Supposing you had to send 100 quantum bits from one laboratory to another -- without teleportation, you would have to send those arbitrarily entangled quantum bits along a wire at the time of the communication. With teleportation, you only need to generate a stream of similiarly-prepared entangled pairs and send one side of them to the other lab. You would also be free to send the pairs beforehand if you like. Given the alternatives it's much more likely that you would use teleportation.

All you folks using dd-wrt, I've shied away from it maybe from ignorance, because I had thought most modern hardware no longer supported it or were flashable, or perhaps had modern hardware and supporting wifi n, or?

Does dd-wrt support modern routers?

I'm not sure why consumer hardware is so hit and miss. You can literally go to the Best Buy and see two routers sitting next to each other on the shelf for approximately the same price. One is trash and one is gold. Why?

You going to pony up the cash for me to read it? Otherwise it's just the same "Uh, we totally transferred data, but not like all those other people who made the same claims before. This is totally legit, bro" article as all the rest over the years.

I do love how the abstract contains this gem: "Combining these two capabilities, here we realize quantum teleportation between two remote atomic-ensemble quantum memory nodes, each composed of ∼108 rubidium atoms and connected by a 150-m optical fiber." It could make sense in some context, but it's pretty funny they'd include that if it didn't facilitate this "teleportation" at all.

That's part of the setup, you have to share entaglement before the teleportation takes place. So basically you don't know the first thing about what is going on. Which is fine, the authors will get along fine without your approval.

Take two boxes in different locations with no common medium and transfer data between them. Then you can start talking about "teleportation" and a quantum network.

If it has been proven that meaningful information can be transmitted without wires or any other ordinary medium and essentially violating the speed of light, we'll eventually find a way to make it work on a larger scale.

Imagine a quantum communication device on a completely automated starship. We'd never have to man the thing, everything is either automated or operated by a human on Earth in real-time (give or take for time-dilation effects). And we could accelerate it much faster than a manned ship, no squishy humans to make accommodations for. We could explore another starsystem remotely. If we found a habitable planet, we could build entire cities for them before settlers finally arrive. A human empire could remain in constant contact, no matter the distance.

/why yes, I do read a lot more sci-fi than I do physics textbooks. Don't judge me for hoping we get off this rock eventually.... and start screwing up whole other planets too.

It's not data, it's quantum information. Nobody said they were teleporting data, you would be dumb to expect it.

The only shared quantum information is the pair, which is done before the experiment. Now I suppose you could call the entangled pair a 'channel' if you wanted, but that runs counter to what people understood an entangled pair to be for 50-60 years.
