Bad Qubits — Learn Quantum by Doing

Multiple choice

In the proposed quantum network protocol stack, what is the primary job of the link layer?

Deliver robust entanglement across one link on demand, hiding the heralded, non-deterministic generation behind a clean request/response service
Provide end-to-end qubit transmission via teleportation
Attempt a single raw entanglement-generation event on one link
Produce long-distance entangled pairs by swapping across many links
