摘要

Many 'paranoid' quantum information processing protocols, such as fault tolerance and cryptography, require rigorously validated quantum hardware. Such hardware (elementary state- and gate-producing components) is calibrated using tomography, by combining many measurement results into a single estimate of the state P or process X. But a point estimate - a single matrix (p or X) that is probably close to the true state P or process X - cannot provide the rigorous validation needed for paranoid protocols. Region estimators, on the other hand, provide just such a guarantee.
