Quantinuum reported quantum error correction performance on the commercial Helios trapped-ion quantum computer, achieving 99.9995% logical memory fidelity with a logical error rate of 5 × 10⁻⁶ (distance-7 code). Using triangular color codes, the work demonstrated exponential error suppression with code distance (Λ = 12) and is aligned with the performance targets of the Apollo universal error-tolerant system aimed for 2029.
