There was one major numerical error I noticed, but then the article corrected itself at the end. This was the error: &gt; With an error rate of 1% the surface error correction code requires ~ 500 physical qubits required to encode one logical qubit. This was the correction near the end: &gt; With an error rate of 0.3% the surface error correction code requires ~ 10 thousand physical qubits to encode one logical qubit to achieve 10^-10 logical qubit error rate. The qubit count at an error rate of 1% was clearly off because the threshold of the surface code…</p><p><a href="https://hackerpaper.kaipfister.de/p/2202.11845/">Paper and discussion history</a>.
