Fundamental rate-loss trade-off for the quantum internet

In a future quantum internet, entanglement or a secret key should be efficiently provided between two points via intermediate nodes connected by optical channels. Here the authors derive general rate-loss trade-off for such protocols, that is applicable to any network topology.
