Extended Data Fig. 4: Numerical simulation for systematic errors of beam-splitters.
From: Scalable and programmable phononic network with trapped ions
We simulate the performance of 50:50 beam-splitters with similar parameters used in the experiment. We achieve population errors induced by (a) heating, (b) motional decoherence, and (c) spin decoherence by subtracting inevitable errors caused by off-resonant couplings shown in Extended Data Fig. 3a. The blue points represent simulation results, with the orange fitting curves representing the error trend. The green stars represent the measurement results of the corresponding values.
