cannot believe I forgot to meme post! thanks for covering for me

Fast surgery for quantum LDPC codes Quantum LDPC codes promise significant reductions in physical qubit overhead compared with topological codes. However, many existing constructions for performing logical operations come with distance-...

happy to share this preprint from last week scirate.com/arxiv/2510.0... - my first with Iceberg!
big thanks to Larry and Nouedyn, who led this cool project ❄️

we have also written a short blogpost about it www.iceberg-quantum.com/blog/fast-su...
comments welcome 🧊

Localized statistics decoding for quantum low-density parity-check codes - Nature Communications Quantum low-density parity-check (QLDPC) codes offer lower overhead than topological quantum error-correcting codes, but decoding remains a key challenge for scalable fault-tolerant quantum computing....

Working on LSD was fun! - Our paper on Localized statistics decoding (LSD) for qLDPC codes is now in print.
LSD is a highly parallelizable, reliability-guided inversion decoder that exploits the clustering of errors. Think of it as a parallel version of OSD.

Next up in session A is Lucas Berent telling us about LSD, a popular topic in Berlin.
