Heterogenous QEC Codes Boost Efficiency In Quantinuum's Helix Architecture
Quantinuum reported experimental validation of its Helix quantum error-correction architecture on the 98-qubit Helios trapped-ion processor. The tests covered logical memory, logical computation, and cross-code logical entanglement, each beating unencoded physical qubit baselines without post-selection.

Quantinuum could use the efficiency gains from heterogeneous QEC codes to demonstrate a logical circuit that outperforms physical qubits on a small but nontrivial computation within two years.
The Helios device already has 98 qubits and high-fidelity operations; the mixed-code approach allocates resources per operation, so if demonstrated logical error rates hold, a few logical qubits could be combined into a shallow circuit with lower overall error than physical qubits without needing full fault tolerance.
