My first question is how fast can it factor large primes? Kiss your 256 bit encryption goodbye if it can do that task at those kinds of speeds. The Feds have been intercepting and storing all the encrypted and VPN traffic they can for a long time for the eventuality of a break through of this type.
All your data traffic are belong to us.
Just did a little research and no, they do not seem to be anywhere near close to having the compute performance needed to attack current cryptographic techniques with even today’s or the near future’s best quantum computers.
