Quantinuum says Helios quantum computer crosses error-correction breakeven

Quantinuum announced this week that its current-generation Helios quantum computing hardware can scale beyond the breakeven point on logical error correction, meaning larger logical qubits reduce errors rather than add them. Observers note every step-up in logical qubit size improves performance, a milestone long seen as essential for practical, fault-tolerant quantum computing.
Why now: Reaching error-correction breakeven is a major claimed milestone on the road to useful quantum computers.
