đŹ BREAKING: Quantinuum Achieves World-Record 99.9995% Logical Fidelity
Official announcement today - Oct 19, 2026 - from Quantinuum ($QNT) Nasdaq:
What was achieved:
On its commercial Helios system, Quantinuum reached 99.9995% logical fidelity using its error-correction architecture. This equals 5 errors per 1 million operations.
Context:
10x better than Quantinuum's own world record from September 2026
100x better than the best published result from other hardware (Google Quantum AI, superconducting system)
Uses a 'color code' within its end-to-end architecture with AI decoders + all-to-all trapped-ion connectivity
Why it matters:
Quantinuum confirmed this performance is within the target range for Apollo, its planned universal fault-tolerant quantum computer expected by 2029.
Key quote from CEO Rajeeb Hazra (WSJ): "We have the world's lowest error rate and the most efficient way to do it. This derisks the industry."
The new approach needs âŒ30x fewer physical qubits per logical qubit than other approaches, making fault tolerance scalable.
Timeline:
Helios: commercial system, already in use
Apollo: full fault-tolerant system, 2029
Source: Quantinuum official press release + WSJ + HPCwire - Oct 19, 2026
Implications for crypto: fault-tolerant quantum accelerates the need for post-quantum cryptography. Chains like $QRL (quantum-secure since 2018, XMSS) and enterprise solutions like $NAORIS / $NAOX become critical infrastructure.
