There's still caveats—only 1 logical qubit, no actual computation, absolute error rate per cycle is 7x per syndrome—but Google's error correction result really is very impressive, and it suggests a real path to fault tolerance. https://www.scientificamerican.com/ ...

When extraordinary claims don't replicate, researchers often have to shrug. But in the case of LK-99, rigorous scientific detective work got to the bottom of what was going on. My reporting on the (probable) end of the LK-99 saga here: https://www.nature.com/...
Nature
Studies show that LK-99 is not a superconductor and that impurities, notably copper sulfide, were responsible for the material's superconducting-like behaviors

@GolinoHudson Yes, I saw that preprint. Decided not to include it in our coverage since it came later and it does not have any measurement of resistance.
Nature
Scientists have so far failed to show that a South Korean team's LK-99 material is a claimed room temperature superconductor, which could transform computing
