- Method
- Not confirmed: two readings disagree: Here we demonstrate below-threshold operation of triangular color codes with distances $d=3,5,$ and $7$ on Quantinuum’s Helios trapped-ion quantum processor. and triangular color code distance-7 memory experiment on Helios trapped-ion processor with SWAP-superdense syndrome extraction and leakage reduction
