Quantinuum Helios achieves 99.9995% logical fidelity
Quantinuum's Helios quantum computer achieved 99.9995% logical fidelity, with only five errors per one million logical operations. The error rate is ten times lower than Quantinuum's own previous record and 100 times lower than Google's best published result, using color code error correction and AI-driven real-time decoding on a 98-qubit trapped-ion system.
Why it matters Achieving ultra-low error rates is essential for scalable, reliable quantum computing, enabling real-world applications in cryptography, materials science, and complex problem-solving within the next decade.
