Can they? Can they really break RSA 4096? Because the algorithm we have to do that just turns it from 256 bits of entropy to 128, which is still not breakable.
Algorithms. Plural. Shor’s and Grover’s. Nothing public that can break anything in use but progress marches on and governments are always expected to be 5-10 years ahead
After quantum. Algorithms for after a quantum computer can crack what’s current.

Hm. It appears I did not know about Shor’s. :/ sorry.
Although I’m willing to bet that it requires an exponential amount of correction qbits.
