Figure 10

Log plots of MSE cost curves for reservoir tuning iterations. MSEs from initial to final iterations improved up to 2.5 orders of magnitude, demonstrating the effectiveness of noise optimization. In the two plots comparing LE and PS reservoirs, it can be seen that there is no notable difference between final MSEs for MG19 or MG25 data up to 12 qubits. By the principle of resource reduction PS reservoirs should be favored. See Methods for details on optimization and simulation matters.
