MODERATORS
There's a lot of misinformation in this thread. Sure, they broke 22-bit RSA encryption. But here's the thing - that's proof that a suitably large quantum computer can break any size RSA encryption in the same amount of time it took to break 22-bit RSA encryption.
Because of the way the annealing process works, it's a known-time process, no matter how many inputs or q-bits are used. We don't have the ability to create a computer with sufficient q-bits to break anything more than 22-bit at the moment, but current estimates are that in 10 - 15 years we will have enough to break 1024-bit.
And it'll take the same amount of time as this 22-bit process took.
And that basically means we need new encryption processes within 10-15 years, that are quantum safe, or all our encryption is belong to whoever has these quantum computers.
