The comparison of the successful probability of image pattern matching using different number CNOT gates based on three algorithms. The title of every subfigure is the target data in its situation, the x-coordinate is all of the measurement outcomes without postselection in three cases respectively and the y-coordinate is the corresponding value. The successful probability of pattern matching is the sum of the probabilities of the results whose \(n_{D}\) bits are represented by the first three digits of abscissa being 0
