A new encoding scheme for exp(-iθP) into stabilizer codes like [[n,n-2,2]] and [[5,1,3]] achieves 4-7x lower noise than unencoded versions with at most 3% runs discarded after postselection.
Evolutionary BP+OSD achieves higher decoding performance and lower complexity than standard BP+OSD on surface and QLDPC codes, especially under low-latency constraints.
Entanglement boosting protocol prepares logical Bell pairs in rotated surface codes with orders-of-magnitude lower link-limited volume, reaching 10^{-10} logical error from 86 physical pairs at 1% error using soft decoders and postselection within one patch.
