Unraveling the Pentagon’s quantum problem

HONOLULU—Preparing for a quantum computer attack means two things: knowing exactly which systems will need to be upgraded and making sure everyone understands how serious the risk is to sensitive data protected by standard encryption.“Our adversaries are using quantum. How advanced are their capabilities? We don't totally know. But the reality is that that presents some threats, and the challenge with, you know, post-quantum cryptography is this idea of ‘harvest now, decrypt later,’” s
