Quantum entanglement seems poised to provide real-time interstellar communication.

That makes for good science fiction, because Quantum Mechanics is so poorly understood by most people, but it’s in no way possible or implied by the theory. Any entangled channel of communication would appear to be random noise without a Classical channel of communication, which effectively limits entanglement to light speed.

The first answer gives a nice explanation in depth. https://physics.stackexchange.com/questions/203831/ftl-commu...

The key point is this:

Alice therefore still measures two overlapping bell curves, overall! Where are the interference patterns?! That is very simple: when Bob and Alice compare their measurements in the first case, Bob's 0-measurement can be used to "filter" Alice's patterns...

That comparison is what requires the Classical channel, and we’re back to light speed. If you try to use a Quantum channel to compare you just have two things to compare and a lot of noise.

I think the best way forward would be Satellite based Internet where people can tune their dish antennas to the sky and get Internet. That would be Interruption free and decentralised. I have very low faith on Bitcoin mining operations to be repurposed for decentralised Internet, though in theory they have the compute nodes no body is free from the Internet service providers. A decentralised network based on existing network can never be totally free or decentralised.

Satellites are decentralized?
