Super nice result from my colleagues @marklt.bsky.social @riverlane.com showing the NP-hard-ness of min-weight colour code decoding! scirate.com/arxiv/2603.0... 🧠

New paper! ✨ scirate.com/arxiv/2507.1... ✨ We present a new family of qLDPC codes that beat the rotated planar code while only requiring square-grid (or even hex-grid!) connectivity. 1/3

Got AMO qubits and love doing transversal gates, but don't know how to decode them efficiently and quickly? Check out this awesome new paper from my very talented colleagues @riverlane.com ! 🧪

Okay obligatory paper meme: Recently Setiawan, at Riverlane, and I released a preprint on how to tailor Floquet codes to noise that is biased towards, say, Z errors. This "X3Z3 Floquet code" could improve performance on architectures using, e.g. the heavy-hex lattice. www.arxiv.org/abs/2411.04974
