A single condition, accurate MSE plus accurate zero-eigenvalue estimates, is necessary and sufficient for optimal infidelity scaling in state, detector, and process tomography, and adaptive algorithms based on it achieve O(1/N) error in numerical and optical experiments.
For a non-trace-preserving process, after the two-step adaptive QPST, we obtain ˆσ out, where Tr (ˆσout)<1 and also reconstruct ˜X0 as Eq

Unified formalism and adaptive algorithms for optimal quantum state, detector and process tomography
A single condition, accurate MSE plus accurate zero-eigenvalue estimates, is necessary and sufficient for optimal infidelity scaling in state, detector, and process tomography, and adaptive algorithms based on it achieve O(1/N) error in numerical and optical experiments.
