[…] a new study shows that, even lacking good error correction, there are ways to mitigate errors that could make quantum computers useful today.

    Just when I think I have a handle on what quantum computing is and start to build a mental model of it, they come up with stuff like this that makes me question myself. I can sort of see how, if the noise had a non-uniform impact on the state of the system how such a thing could be possible. But the fact they actually have managed to do it is amazing to me!
