Quantum Teleportation Success via Internet

For the first time, quantum communication was realized via an existing Internet line. In this video, we'll discuss this new method of communication over a 400 Gbps (Gigabit per second) fiberoptic cable with a length of 30.2 km. Science is great and inspiring.

All right then, keep your secrets.

Don’t forget Ai quantum mechanics. Those two are a handy go to too.

To be clear, this has nothing to do with the fabled instant communication of "Quantum Entanglement Communication." The only real benefit to any of this is more secure messaging. That is to say that you can communicate 100% securely. As in if the signal is intercepted, it decoheres in a way that the signal to noise ratio is functionally identical to 0:∞ meaning the only reason to even TRY to intercept the data is to screw up the transmission of the data and prevent its delivery.

I wish I understood this but it seems really cool+1

But if it's quantum, wouldn't the message change when you tried to listen to it!? S/

Hi, the website https://opg.optica.org/optica/fulltext.cfm?uri=optica-11-12-1700&id=565936 contains a diagram of the experiment (Fig. 1). Alice's qubit is destroyed.

Yes and no, depending on how you look at it /s

A permanent ping of 0 ms and 0 latency. A gamers fucking dream.

That's not what this is. That would violate No Cloning Theorem. There is no known way to do that. This is far less flashy. What it actually means 100% truly secure encrypted communications with no chance of interception.
NChomsky
Oh. Not interested, then.... Just kidding. I guess obvious joke wasn't so obvious. I understand this doesn't allow for faster-than-light communication (classical communication channels are obviously limited to sub-light speeds anyway). I should've thrown an /s on there or something.

I mean it's a benefit, it's just not the stuff of science fiction :(

Look on the bright side, yesterday's science fiction sometimes does become tomorrows reality. Space travel, submarines, AI, VR, robotics/robotic helpers, friggin' cloning. Shit even the gods damn Internet itself. Even ideas that clearly violate physics have come to be realized, just in clever ways that don't violate physics. Science fiction has often been the inspiration for very real and cool things.
