PhD student working in quantum error correction
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 🧊
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-...

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.

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....
