I think this is the SOTA https://s7d9.scene7.com/is/content/quantum/LQ_ErrorCorrectionpdf https://s7d9.scene7.com/is/content/quantum/LQ_ErrorCorrectio... the corrections significantly decrease the error rate but they need to do a lot of preselection, so it isn't quite useful yet.

Thanks! If I'm reading that correctly, their best error rate with pre and post selection is 0.03%, but they end the paper with the statement "A significant milestone will be to demonstrate a universal family of quantum circuits with logical error rates approaching 10^−8." Seems like we're still six orders of magnitude off.

  IIRC We're just over 1 order of magnitude on the physical qbit error before we should see the exponential gains from error correction that theory predicts.
