Cubical Sheaf Complexes with Constant Expansion with Applications to Asymptotically Good qLTCs

Yeyuan Chen, Miryam Mi-Ying Huang, Yinchen Liu +1

For every fixed integers $r\ge 4$ and $2\le k\le r-2$, we construct $r$-dimensional cubical sheaf complexes whose degree-$k$ CSS codes have positive constant rate, linear distan…
