Well, the way that immediately comes to mind would be to send two packets per transmission. One that is point-to-point, which contains the routing information, and one that is meant to be routed without being read, but there must be something more to it as this solution seems too simple to have not been thought of.

Their approach is to create a quantum network based around a hub and spoke-type network. All messages get routed from any point in the network to another via this central hub. This is not the first time this kind of approach has been tried. The idea is that messages to the hub rely on the usual level of quantum security. However, once at the hub, they are converted to conventional classical bits and then reconverted into quantum bits to be sent on the second leg of their journey." With a little more reading, it seems like the issue they face now is the reliance on a secure central hub.
