Comment on Test of a prototype quantum Internet runs underneath New York City for half a month
QuadratureSurfer@lemmy.world 3 weeks agoThat’s a big misconception with what quantum internet is (and what quantum entanglement actually allows for) as explained by this physicist: 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.
