Abstract
We redesign the parameterized quantum circuit in the quantum deep neural network,construct a three-layer structure as the hidden layer,and then use classical optimization algorithms to train the parameterized quantum circuit,thereby propose a novel hybrid quantum deep neural network(HQDNN)used for image classification.After bilinear interpolation reduces the original image to a suitable size,an improved novel enhanced quantum representation(INEQR)is used to encode it into quantum states as the input of the HQDNN.Multi-layer parameterized quantum circuits are used as the main structure to implement feature extraction and classification.The output results of parameterized quantum circuits are converted into classical data through quantum measurements and then optimized on a classical computer.To verify the performance of the HQDNN,we conduct binary classification and three classification experiments on the MNIST(Modified National Institute of Standards and Technology)data set.In the first binary classification,the accuracy of 0 and 4 exceeds 98％.Then we compare the performance of three classification with other algorithms,the results on two datasets show that the classification accuracy is higher than that of quantum deep neural network and general quantum convolutional neural network.
