The advent of quantum computer has generated tremendous repercussions not only in the computer field but also in physics, communications, materials, and many other fields. Now many countries have joined the development of quantum computers. There is a lot of progress in quantum algorithms, construction, physical implementation and other aspects. With the progress of information technology, people's demands for data processing and speed become increasingly harsh, in this context, the combination of quantum technology and big data processing technology breaks through the dawn of big data processing.
