A very useful video that explains what Quantum Internet is... and what it isn't:

TL/DW: A big misconception here has to do with Quantum entanglement. Quantum Entanglement in Quantum Internet doesn't mean that you can transfer data at speeds faster than light.

It's true that this connection would be "ultra secure" but this would be very inefficient (slow) and it wouldn't be reliable in a noisy environment. It would probably be most useful for some sort of authentication protocol/key sharing.
