## Quantinuum Helios Result
Quantinuum's Helios trapped-ion quantum computer reached 99.9995% logical fidelity, a tenfold improvement over its September record.
## Error Correction Improvement
The result is 100 times better than Google Quantum AI's best published figure from competing hardware.
## Code Distance Scaling
Each increase in code distance cut remaining errors by a factor of 12, showing error suppression scalability.
## Apollo Target
Quantinuum's fault-tolerant machine Apollo is targeted for completion in 2029.
## Financial Performance
Quantinuum reported $8 million in second-quarter revenue and $2.1 billion in cash after its IPO.
## Error Correction Scheme
Quantinuum used a color code requiring up to 37 physical qubits per logical qubit for error correction.
## Expert Assessment
Sandia National Laboratories' Robin Blume-Kohout called the result a milestone for quantum error correction.
## Resource Efficiency
Quantinuum estimates a future machine could support 100 protected logical qubits with 30,000 physical qubits.
## Key takeaway

Quantinuum's Helios quantum computer achieves 99.9995% logical fidelity, 100 times better than Google's best result.
