Minimum Weight Decoding in the Colour Code is NP-hard
All utility-scale quantum computers will require some form of Quantum Error Correction in which logical qubits are encoded in a larger number of physical qubits. One promising encoding is known as the...

New paper! โจ

โจ 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

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.
