the point here is that they used a fiber optic which was already carrying internet traffic to send half of a bell state and then did quantum teleportion using the classical channel (see my other comment for explanation of what quantum teleportation is).
sending quantum states has applications like networking quantum computers, but also stuff like Quantum Key Distribution which is fundamentally impossible to eavesdrop on due to results like the no-cloning theorem! its like public key cryptography but the security is guaranteed by the known laws of physics.
Wait so could you keep two computers in sync by sending each one half of this bell state thing but with no direct communication between the two synced computers?
no the point is that you can transfer /quantum/ states by only directly sending /classical/ information
nope, anything with quantum needs a point-to-point connection per server. If you have multiple servers, you need to connect everything to everything else individually. This stuff is not networkable.
