Extended Data Fig. 4: Comparison of experimental model and data.

Including a 3% source of infidelity in our model (which otherwise consists only of independently determined parameters) is sufficient to account for the offset observed between our model and our experimental data. a, The modified model, plotted with experimental data reproduced from Fig. 4. Dashed lines show the model given in the main text (without the infidelity parameter). b, This infidelity also applies to the model shown in Fig. 3, because an equally large number of entanglement repetitions was used in generating the data. Error bars for data and shaded model uncertainties are 1 s.d.
