Quantinuum Helios Test

Quantinuum Quantum Error Correction Fidelity Hits 99.9995%, Just 5 Errors Per Million Operations

Quantinuum's commercial ion-trap quantum computer Helios achieved 99.9995% logical fidelity in error-correction testing.

Error Rate Improvement

The result shows 5 errors per million operations, a 10-fold improvement over Quantinuum's September record.

Comparison to Google

This is roughly 100 times lower than Google Quantum AI's best publicly disclosed superconducting result.

Code Distance Effect

Code Distance Effect

Each increase in code distance reduced logical errors by about 12 times, showing exponential improvement.

CEO Statement

CEO Rajeeb Hazra said the company has the architecture to achieve universal fault tolerance by 2029.

Industry Impact

Experts say the result eliminates a core technical risk in quantum computing development.

Financial Challenge

Quantinuum lost $65.4 million on $8 million in revenue in the latest quarter.

Apollo Roadmap

The Apollo system, a fault-tolerant quantum computer, is scheduled for launch in 2029.

The bottom line

Quantinuum's Helios quantum computer reached 99.9995% logical fidelity, showing 100x better error correction than Google's superconducting systems.
