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?"

But how did that same reading get there?

Meanwhile, physicists have not teleported quantum information from one ensemble of atoms to another 150 metres away, a demonstration that doesn't pave the way towards quantum routers and a quantum Internet.

Imagine what kind of bullshiat is going to come from hackers being able to remotely flip bits of in-use memory at the physical level from across the street or internet? Man, yuck. Firewall? 7 Boxxies? Nope, the freakin tinfoil sportin' Faraday cagers will actually have their day in the sun. (where they will get a terrible burn and retreat back to the basement).

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.

Netgear WNDR3700 running DD-WRT with torrents, usenet downloads running, 7 computers (one a VM server), tablets, smart phones, game consoles, smart TV, networked home theater receiver, and networked BD Players... haven't rebooted it in a couple of months.

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.

/not a scientist, but knows way more than science-journalists... sadly.

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?

We have tons of those running at client sites. And I have one at home (slightly older version), and they don't ever need to be rebooted. Ever.

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?
