a, b, Noiseless (a) and noisy (b) numerics for an initial Néel state with g/J0 = {0.24, 1.2, 1.8} (light to dark), corresponding to the data in Fig. 2c. Compared to the ideal numerics, the noisy numerics show overall lower imbalances, primarily due to the SPAM errors, and damped oscillations, primarily due to variations in the individual local effective Bz fields. However, these noise sources do not strongly affect the stability of the imbalance. c, Individual noisy realizations corresponding to the highest gradient shown above. d, Noise-averaged DEER simulations corresponding to Fig. 3b.
