New arXiv qLTC paper ships an Astra-generated companion draft, a first for quantum coding

Igor Carron highlights that the authors of a new arXiv paper, "Cubical Sheaf Complexes with Constant Expansion with Applications to Asymptotically Good qLTCs" (arXiv:2609.28028), publicly shared a companion draft generated by Astra alongside their submission.

The paper itself is quantum information theory: it constructs r-dimensional cubical sheaf complexes whose degree-k CSS codes have positive constant rate, linear distance, and constant soundness; taking r=4, k=2 yields a family of asymptotically good binary qLTCs. The core is a uniform product-expansion theorem for explicit Reed-Solomon codes on norm-one evaluation sets, combined with the Dinur-Lin-Vidick local-to-global framework and sheaf duality.

Notable signal: fully AI-generated paper drafts are now appearing as public companions to formal arXiv submissions.
