I don't see it as much as a QKD advancement but as a Satellite and tracking advancement, as you have to somehow receive individual photons from earth while orbiting at 30 km/s. And if you can track your satellites this accurately, you can track everybody elses. On 11/08/17 03:41, Jean-Philippe Aumasson wrote:
Mostly PR I believe. With this satellite-QKD thing the Chinese probably want to show their own expertise (if they built this alone and not with Western companies), whereas a couple years ago they were discussing with IdQuantique and others to build QKD backbones. Are the Chinese into "quantum supremacy" projects like Europeans? I don't see satellite-QKD as a way to defeat future (?) quantum computers, cos satellite-to-earth coms are usually symmetric-crypto based, something unbroken by a QC. BTW QKD research doesn't have much to do with QC.

Did they study up and learn something themselves that we are not aware of? Or is this a total lark or PR stunt? Or maybe it's just not that much money to them, so they might as well? -dave _______________________________________________ Dailydave mailing list Dailydave () lists immunityinc com https://lists.immunityinc.com/mailman/listinfo/dailydave_______________________________________________ Dailydave mailing list Dailydave () lists immunityinc com https://lists.immunityinc.com/mailman/listinfo/dailydave
