Figure 6From: Real quantum amplitude estimationNumber of calls to the oracle \(N_{\text{oracle}}\) versus the required precision ϵ. The picture is in a log-log scale with the x-axis inverted. The experimental points (circles, squares and diamonds) represent the mean number of oracle calls obtained by the experiments while the error bars stretch from the maximum to the minimum value obtained in the same experiments. The lines are the corresponding theoretical bounds from Equation (29)Back to article page
