Concatenating (3,4)-random hypergraph product codes with distance-5 rotated surface codes yields a lower logical error per qubit than a distance-25 rotated surface code when the top-code size parameter is at least 4.
Although computationally efficient, this method reduces the effective code distance to: deff = 2 d1 + 1 2 d2 + 1 2 , (7) 4 FIG

Hierarchical Quantum Error Correction with Hypergraph Product Code and Rotated Surface Code
Concatenating (3,4)-random hypergraph product codes with distance-5 rotated surface codes yields a lower logical error per qubit than a distance-25 rotated surface code when the top-code size parameter is at least 4.
