It can be seen that regardless of the initial fidelity, the fidelity enhancement efficiency, i.e., the ratio of fidelity improvement to resource consumption, is the highest one for the one-round purification scheme, i.e., the fidelity improvement from the one-round purification scheme is the largest for the same resource consumption.
