The quantum gate type quantum computer has high versatility and can be expected to be put into practical use in short future. However, the quantum bits of the quantum gate type quantum computer are very weak against external interference, and it is difficult to maintain the quantum state for a long time. Therefore, in the currently developed quantum computer, the number of quantum bits is limited, so it is difficult to calculate large scale and high dimensional data. In this paper, as a solution to this problem, we proposed a computation method that applies convolution filter, which is one of the methods used in machine learning, to quantum computation. Furthermore, as a result of applying this method to the quantum auto encoder, we found the effectiveness by applying convolution filter constituted several qubits to the data made of several hundred qubits or more under the autoencoding accuracy of 98%.
