Spaced X-gate trains and the decay-bookkeeping control, 2 and 4 October 2026

Every number in the paper’s section on spaced X-gate trains, recomputed from the raw IBM job results: 13 jobs on ibm_pittsburgh, ibm_marrakesh and ibm_kingston (job IDs in the output). verify_xtrain.py prints each paper value beside the recomputed one (output); 79 of 83 matched at the first recomputation and the paper was corrected for the other four. The 4 October pittsburgh sweep now uses all three of its jobs (script, output; start |1⟩ against start |0⟩: script, output). The raw job files (218 MB) are in the Zenodo deposit under the same folder name; the script reads them from data/.
