Fig. 3: Transferability of parameters in QAOA with Zeno dynamics.
Performance of a 1-layer (a) and 5-layer (b) QAOA with Zeno dynamics and mixer B = ∑jxj with directly optimized parameters (ropt, 1 − δopt) and with parameters transferred from a fixed value of η = 1.6 (rtran, 1 − δtran). The source is marked with a star. Corresponding to each case, r signifies the approximation ratio and δ the out-of-constraint probability. For values of the hyperparameter η, which controls the number of measurements and is defined in Equation (11), smaller than 1.6, the difference between performance with optimized and transferred parameters is negligible (dashed line very close to the solid line).
