Abe Lincoln knew the truth about QKD.
He's attributed to have said "You can fool all the people some of the time and some of the people all the time, but you cannot fool all the people all the time."
But that's exactly what quantum deniers (QD) are espousing. Any relation to QA? The banks, the governments (https://spacenews.com/governments-ally-for-federated-quantum-encryption-satellite-network/), the universities, the militaries, Europe (https://spacenews.com/europe-picks-euroqci-satellite-quantum-communications-consortium/) are all going for QKDNs because they're secure when correctly implemented. They allow mathematically unbreakable one time pads to be distributed and used.
But of course they're all fools. We here know the truth, eh?
