  How do people test post-quantum cryptography? How do they verify their encryption can not be defeated by quantum computing without having access to real world quantum computing? Are they basing everything off theories?

  Best be ready, for Q-day:

  > The looming ‘Q-Day’ should also be used as the stick to get approval to carry out a cryptographic inventory and roll out projects that foster cryptographic agility more generally.

  > Q-Day will not be announced and businesses need to take action now in the face of a growing threat.
