I think it should be noted explicitly, that this is just quantum encryption on the link level, so the data is secure on the fibre, but apparently needs to be decrypted at the router. So this is a nice application, but simply does not solve most security needs. ( Except protecting against and adversary who is willing to splice into the fibre, if you happen to control all endpoints and the intermediate routers.)
