I am worried about the future of quantum tokens...
Whilst theoretically they are secure, I worry about potential huge side-channels allowing leaking of the key...
All it takes is a few extra photons emitted at some harmonic frequency for the key to be leaked...
I would much prefer dumb hardware and clever digital software, because at least software is much easier to secure against side channels, and much easier to audit.
