Helios (Nov 2025): 98 physical qubits, 50 logical qubits, 99.9975% 1Q and 99.921% 2Q gate fidelity. All-to-all qubit connectivity. Quantum Volume 33,554,432 (2^25, Sept 2025). Microsoft partnership (2024): demonstrated 4 logical qubits across 14,000 experiments without a single error. H2 (56 qubits) achieved QV 1,048,576 (2^20) in 2024. Software: InQuanto (quantum chemistry), Quantum Origin (cybersecurity entropy source), and lambeq (quantum NLP/AI). In September 2026, Quantinuum validated its Helix error-correction architecture on Helios: logical memory, logical Clifford computation, and logical entanglement across different codes each outperformed the corresponding physical-level result without post-selection, providing the stated architectural foundation for Apollo. In October 2026, Helios achieved 99.9995% logical-memory fidelity—five uncorrectable errors per million operations—with each tested code-distance increase reducing memory errors by an average factor of 12 and logical-gate errors by an average factor of 9.
