But how is the latency for online gaming? It’d be awesome if it’s near instantaneous, or limited only by the net code.

    Can someone explain why they still need fiber? I thought this was about someone finally succeeding in making practical use of entangled pairs.

      Entangled particles cannot transmit information between the pairs. That would violate information theory and likely causality as well.

      Quantum networking is instead focused on using extremely robust encryption that can detect interception using entangled pairs of light particles being transmitted together in the fiber optics.

        some interpret this to mean there is no free will.

        Which is kinda stupid. Because even if my decisions come about through undetermined random quantum effects that is still a physical effect outside of my control and I still cannot really act of my own free will. Schopenhauer had already figured that out without the need for quantum physics. A person might do what they want but they cannot want what they want.

        tldr: Free will is bullshit. Let’s watch some TV.

      That’s a big misconception with what quantum internet is (and what quantum entanglement actually allows for) as explained by this physicist: https://www.youtube.com/watch?v=u-j8nGvYMA8

      Quantum Internet doesn’t mean that you can transmit data faster than the speed of light.

      Quantum Internet just means you get an ultra secure connection, but it’s super susceptible to noise (in other words, you can’t send a lot of data reliably and it would be terrible for that).
      At best this would be useful for being absolutely sure that some encryption keys were sent successfully without being intercepted by anyone else.

        This is one of the few instances where it’s appropriate to post Sabbine, and she isn’t spreading misinformation. I used to enjoy watching her videos. On topics of physics she’s good. But holy hell some of the shit takes she’s had deviating from the areas she’s educated in.

    Come check out Comcast’s New Quantum Internet plans! Up to instantaneously Download speeds and almost 40 mbs Upload speeds! Amazing! And if you get our route we’ll make you pay for it forever, and then charge you for it if it doesn’t look new when you return it! Life changing! Don’t forget our data caps! While it cost us a fraction of a fraction of what we charge you to send slightly more or less of your data we’re gonna charge ya for it anyway because fuck you! Bend over!

      Absurd. Comcast would never dare offer upload speeds as high as 40 millibits per second.

    Mom, can we have a quantum-entangled network?

    Mom: No, we have a quantum-entangled network at home.

    Quantum-entangled network at home:

      Everyone hating on that setup are a bunch of morons.

      There’s a good reason to put your patch panels on a separate rack then all of your switches like that, and eventually you’ll have to roll them around. At which point, you’re going to need some slack in the lines, like when you’re hooking up a tow line to your hitch.

      That’s all I see here, preparedness. Separate racks for switches and patch panels, and a lot of slack for when you got to roll them around, or some shit I don’t know.

      I just know that I see foresight and planning when I look at that picture, not sure why everyone else doesn’t.

      That’s just a demonstration of entropy. Every network rack without an admin to whack techs over the hands with a ruler will eventually look like this.

      Tech 1: wow, I’m am so proud of this work

      Tech 2: hmm, this bundle has a couple wires poking out and going in random directions, I don’t need to pay attention to mine that much.

      Tech 3: huh, racks a bit messy, no problem I’ll just toss this here cable up and over the back

      Tech 4: just drapes it across the floor

      Tech 5: burns it down GOTO tech 1.

    With my limited knowledge in the subject, after reading their paper, what I understand is, although they say it like it was a great success, their experiment, in its current state, will fail at scale. But, it is a progress compared to previous methods. Also, photons do not play nice.
