Figure 10. SWIPER-SIM program traces for a 15-to-1 magic state distillation in a distance-7 code using the construction from [24] (Fig. 17). Time advances vertically, and each horizontal slice represents a batch of syndrome data (colored by instruction type). Decoding time is fixed to be the same as the time to generate 2d rounds, about twice the window generation rate. Device traces are shown for (a) baseline parallel window method (15.1d QEC rounds) and (b) SWIPER aligned window (11.3d QEC rounds, a 25% improvement).
