Detector error model for a circuit with post selections

Quantum Computing SE Archived Mar 17, 2026 ✓ Full text saved

Consider a circuit which has measurements which are used for post selection, i.e., at any time the measurements flip, the shot is discarded. Then, after this, the circuit also has measurements used for decoders, i.e., detectors. In this case, how can we construct the detector error model used for decoding? A typical circuit that has this structure is magic state cultivation. In one sense, I feel like an error before the post-selection measurements should not be accounted for an error mechanism f

    Detector error model for a circuit with post selections Ask Question Asked today Modified today Viewed 4 times 0 Consider a circuit which has measurements which are used for post selection, i.e., at any time the measurements flip, the shot is discarded. Then, after this, the circuit also has measurements used for decoders, i.e., detectors. In this case, how can we construct the detector error model used for decoding? A typical circuit that has this structure is magic state cultivation. In one sense, I feel like an error before the post-selection measurements should not be accounted for an error mechanism for the detector error model because it does not flip the detectors. It is discarded. On the other hand, I also feel that with measurement errors on the post-selection measurements, such error can also affect the detector error model. Should errors before the post-selection measurements be also counted as error mechanism of subsequent detectors? In Stim, how can we get the right detector error model in this kind of situation? error-correctionstim Share Improve this question Follow asked 1 hour ago lan 3211 1 silver badge 7 7 bronze badges Add a comment Know someone who can answer?
