Quantinuum Reports a 10x Reduction in Logical Error Rate on Helios
Quantinuum announced that its Helios commercial trapped-ion computer achieved a logical fidelity of 99.9995%, corresponding to a tenfold reduction in logical error rate. The company attributed the result to its error-correction architecture and said it is its second error-correction advance in two months.

If the demonstrated logical fidelity persists when multiple logical qubits are entangled, Quantinuum could run small fault-tolerant circuits on Helios-class systems within two years, providing an early error-corrected testbed for customers.
The 99.9995% figure likely reflects a single logical qubit or a limited operation set. The next precondition is maintaining that fidelity across multi-logical-qubit entangling gates and managing overhead; if achieved, it shifts the system from isolated logical-qubit records to small but usable error-corrected computation.
