Note that you do not need error correction for quantum computing. You only need it for digital quantum computing. There's a separate branch, analog quantum computing, that is also very promising.

Does anybody want to elaborate why I'm being downvoted?
For context, there are several companies selling analog quantum computers, e.g. Pasqal, D-Wave.
What D-Wave has is not a quantum computer, in the sense that it (the computer architecture) can't solve BQP problems efficiently. They are widely considered shills by the quantum computing community.
