SCALA is a signaling cellular automaton with local attraction that achieves ~7.5% threshold and p_L proportional to p^{d/4} scaling for toric codes while keeping computation strictly local and robust to measurement and decoder noise.
Additional to data-qubit noise with ratep, we sub- ject all signal bits at the end of each CA step to bit-flip errors with ratep sig
