The decision on the table
A controller tested against textbook white noise can pass and still fail against the disturbances it meets in service. A safety sign-off is only as good as the disturbance model behind it.

Sign off an autonomy controller as safe against real disturbances
A disturbance model measured on a 128-qubit processor was the only one that certified a controller safe at its operating point.
Headline result
95.6% vs 39.5% safe episodes
95.6% safe episodes with the measured disturbance model, same controller, same operating point
Measured on quantum hardwareClassical computation
What we did, with proprietary methods
We measured a disturbance model on a 128-qubit quantum processor and used it, alongside the standard white-noise model, as the input to a safety monitor that evaluated the controller at its operating point in simulation.
What it was worth
95.6% safe episodes with the measured disturbance model, same controller, same operating point
A safety verdict you can defend
- Baseline
- The standard white-noise disturbance model: 39.5% safe episodes
- Condition
- 95.6% safe episodes with the measured disturbance model, same controller, same operating point
What happened next
The measured disturbance model was the only one under which the controller was certified safe at its operating point. That is the verdict the team can defend: 95.6% safe episodes against 39.5% under white noise.
