Quantinuum's quantum computer hits 99.9995% accuracy
Quantinuum said its 98-qubit commercial quantum computer Helios achieved 99.9995% logical fidelity, meaning just five errors per million logical operations. According to the company, this cuts its error rate 10x versus its previous record and 100x versus Google Quantum AI's best published result. The result is presented as a step toward Apollo, its planned fault-tolerant system due in 2029.
