As far as I can tell, QKD is mainly useful to tell people to separate out the traffic that is really worth snooping onto a network that is hard to snoop on. It is much harder for someone to spy on your secrets when they don't pass through traditional network devices.
Of course, it also tells a dedicated adversary with L1 access exactly where to tap your cables.

Isn't it possible to measure a photon state without causing state collapse by measuring adjacent particles affected by the passing photon? Is it possible to have entanglement communications without such measurement capacity?
