I'm very new to quantum computing, sorry if this is a dumb question.
I was reading in some lecture notes I found online that a quantum network could be created by using teleportation multiple times to move a qubit from one node to the next until it reaches its destination. So, like if you wanted to get a qubit from point A to point D, you could send it from A to B, B to C, and then C to D. At each step, you would send 2 classical bits and use them for quantum teleportation of a qubit.
2 bits A -> B 1 qubit A -> B 2 bits B -> C 1 qubit B -> C 2 bits C -> D 1 qubit C -> D
So I guess my question is, would it be possible to send the necessary classical bits from A to B to C to D, and then use those to directly perform quantum teleportation from A to D? And if so, what is the advantage of performing quantum teleportation at each step?
2 bits A -> B 2 bits B -> C 2 bits C -> D 1 qubit A -> D
