Localized statistics decoding: A parallel decoding algorithm for quantum low-density parity-check (qLDPC) codes. scirate.com/arxiv/2406.186…

Tired of quantum error correction feeling like a bad trip? Fear no more! Meet our new method: Localized Statistics Decoding (LSD). Today's the day that we bring it to the masses! scirate.com/arxiv/2406.186… (1/7)

Introducing BP+LSD: a faster and parallelisable successor to BP+OSD for decoding quantum LDPC codes.

Happy to finally release our work on quantum rainbow codes, a fun collaboration w/ Tom Scruby & Mark Webster! 🌈 Generalizing color codes, we construct a new class of LDPC codes that can have non-Clifford gates, constant rate and growing distance scirate.com/arxiv/2408.131… 1/N 🧵

Today we introduce the BP+OTF decoder (scirate.com/arxiv/2409.014…), an almost-linear time decoder for quantum LDPC codes. Importantly, we aim to do so for circuit-level noise. 🧵

New paper out today with colleagues from Donostia-San Sebastian. A linear-time decoder for QLDPC codes and a new method for sparsifying detector error models.

Our new work on using cavity-assisted neutral atoms for implementing non-local LDPC codes like hypergraph product is now on arXiv! 🚀 Gopikrishnan Muraleedharan Gavin Brennen Check out the full details here: 🌐🔗 arxiv.org/pdf/2409.05818

Can we create noise-optimised colour codes similar to the XZZX surface code? Yes! Domain wall codes offer a general framework for bias-tailoring colour codes. See our new PRL for examples including XXXZZZ codes, XXZZZZ codes, XZXZXZ codes, and many more permutations...
