Test of a prototype quantum internet runs under New York City for half a month
phys.org
To introduce quantum networks into the marketplace, engineers must overcome the fragility of entangled states in a fiber cable and ensure the efficiency of signal delivery. Now, scientists at Qunnect Inc. in Brooklyn, New York, have taken a large step forward by operating just such a network under the streets of New York City.

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

      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.

    Mom, can we have a quantum-entangled network?

    Mom: No, we have a 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, because 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.

    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.
