Bond dissociation energy from noise-prone measurements of emulated hardware, using two error mitigation schemes. (a) state preparation and measurement (SPAM) error mitigation. (b) post measurement symmetry verification (PMSV). In both cases, the same 4 randomisation seeds are used, and plotted as a function of the number of measurement shots. We note that SPAM mitigation and PMSV can lead to different results when calculating ΔE. The fragmentation corresponds to that of Fig. 2b
