In Stim, how to convert a measurement record relative offset to its absolute offset?

In Stim, how to convert a measurement record relative offset to its absolute offset? Ask Question Asked today Modified today Viewed 2 times 0 Referring to this stackoverflow question, it appears very useful, when using a TableauSimulator in multiple passes, to derive the absolute offset of a measurement record of a detector target, e.g.: k = len(measurement_record) + t.value Indeed, this allows the developer to understand, for each detector target, what its value is after simulation. Unfortunately, it seems to me that this line is susceptible to errors, at least in the following context: let's assume I do multiple decoding rounds, and only use the TableauSimulator after N rounds. The t.value component of the detector targets is relative to when the measurement instruction has been first scheduled. Multiple rounds will have the same t.value components, even if they refer to distinct measurements in time. This is due to the fact that we only have relative offsets. It seems to me that there is no easy bijection between the measurement record and the entries of the current_measurement_record() output. Is there any official way, in Stim, to derive this correspondence between a given Detector Target and its absolute offset in the current_measurement_record() output array? I understand that it may be "easy to derive by hand", but, to avoid programming mistakes and because of its usefulness, I wonder whether the Stim API actually supports this and I may have missed it. stim Share Improve this question Follow asked 1 hour ago Marco Venere 1 New contributor Add a comment Know someone who can answer?
