European Space Agency wants in on quantum comms satellites


Don't you kinda need to be in physical control of the optics generating and measuring the photons at the two terrestrial endpoints to have any kind of certainty though...? Once you convert back into the plain digital domain, don't you have to trust whoever else owns the actual hardware that what he's telling you is true and your bits are untampered-with? I know I would see no reason to trust anyone with that sort of thing.
