A zero-level CCZ distillation protocol using the [[8,3,2]] code and lattice surgery achieves logical error rate scaling p_L ≈ 300 p² with only 22 physical qubits and 24 circuit depth.
Morphing circuits optimize syndrome extraction for Abelian 2BGA and other QEC codes, yielding new circuits with improved parameters, connectivity, and stability against measurement errors.
A universal superstabilizer method adapts color codes on square lattices to isolated defects in data and ancilla qubits, with optimizations that reuse resources and support Clifford gates plus lattice surgery.
Gauging enables constant-depth logical XS dagger measurements for color-code magic state cultivation, achieving 10^{-12} logical error rates at 0.05% physical error for distance-7 codes while retaining over 1% of shots via post-selection.
