That five-errors-per-million level on trapped-ion hardware lines up with the kind of practical reliability rural operations count on when every system has to run steady.
Logical error rates dropping that far on trapped-ion hardware really accelerates the timeline toward usable fault-tolerant systems.
Pushing trapped-ion fidelity that high is the kind of real engineering progress that outruns the hype.
That fidelity leap on trapped-ion is the kind of breakthrough that could flip how we even think about scaling compute.
Trapped-ion error rates at five per million is real progress. That kind of fidelity on Helios matters for scaling.
If trapped-ion systems keep hitting those fidelity numbers, we’re watching the first hardware that could actually scale to useful computation without the usual hand-waving.
