Consistency testing for robust phase estimation

We present an extension to the robust phase estimation protocol, which can identify incorrect results that would otherwise lie outside expected statistical range. Robust is increasingly a method of choice for applications such as estimating effective process parameters noisy hardware, but its robustness dependent on noise satisfying certain threshold assumptions. provide consistency checks indicate when those thresholds have been violated, be difficult or impossible test directly. these several common models, and two possible with high accuracy in locating point run at further estimates should not trusted. One may chosen based resource availability, they used together order additional verification.
