Depending on who you ask, the big news this week is that quantum computing researchers out of China have broken RSA. And that’s true… sort of. There are multiple caveats, like the fact that this proof of concept is only factoring a 22-bit key. The minimum RSA size in use these days is 1024 bits. The other important note is that this wasn’t done on a general purpose quantum computer, but on a D-Wave quantum annealing machine.
