Abstract

Constructing quantum codes with good parameters and useful transversal gates is a central problem in quantum error correction. In this paper, we continue our work in arXiv:2502.01864 and construct the first family of asymptotically good quantum codes (over qubits) supporting transversally addressable non-Clifford gates. More precisely, given any three logical qubits across one, two, or three codeblocks, the logical CCZ\mathsf{CCZ} gate can be executed on those three logical qubits via a depth-one physical circuit of CCZ\mathsf{CCZ} gates. This construction is based on the transitive, iso-orthogonal algebraic geometry codes constructed by Stichtenoth (IEEE Trans. Inf. Theory, 2006). This improves upon our construction from arXiv:2502.01864, which also supports transversally addressable CCZ\mathsf{CCZ} gates and has inverse-polylogarithmic rate and relative distance.
