This is an extension of my DEFCON 23 talk “Quantum computers vs computers security” where I’ll tell you more about the recent 1000-qubit processor and about postquantum crypto’s latest developments. I’ll also tell you how today’s encryption systems are affected (PGP, TLS, OTR, and others) and what you should do if you believe that quantum computers will soon be working.
