So there's a lot of incorrect assumptions and outright wrong ideas of how quantum entanglement is going to be used in a quantum network, or even a quantum Internet.
A hard rule: information cannot be sent faster than the speed of light.
When news articles try to summarize quantum teleportation, they incorrectly imply that information is being transmitted instantly. Quantum entanglement is not intended to send information. It's meant to act like a hash or checksum. The magic in it is it enables both sender and receiver to know that their communication has been tampered with.
It has further use with encryption, but again, it's to facilitate the encryption. The information is still being transmitted as light through the fiber network.
