The key point of introducing quantum genetic algorithm to a quantum backpropagation neural network model is to overcome local stagnation problem which used to be Achilles' heel. In this paper, we propose a new quantum backpropagation (QBP) model based on the quantum genetic algorithm (QGA) and make simulations with this model to see whether QGA can really upgrade QBP and, in addition, to ensure that both quantum neural networks are better than classical backpropagation (CBP) neural networks from many points of view. Numerical experiments have been built to illustrate the efficiency of the new QBP algorithm over CBP and the original QBP algorithm. However, the proposed model has shown superior results to the rest of models in terms of correction rate and training time. That is to say quantum genetic algorithm-based quantum backpropagation neural network converges earlier than the other two models and that's why we can reduce the time needed to train.
