General quantum computer refers to the equipment that can conduct
quantum computation and other quantum information processing for all
computable problems without changing the physical composition and basic
architecture of quantum computer. The research and manufacture of universal
quantum computers have important theoretical and practical significance. In
order to achieve the goal of making universal quantum computer, efforts should
be made in many aspects, such as the underlying quantum physics equipment,
the quantum computer architecture, the quantum resource scheduling and
the upper quantum programming language, the quantum algorithm and the
quantum application software. In this paper, the author draws a blueprint for
the research and manufacture of universal quantum computer from the point
of view of computer system, and elaborates the difficulties and the direction of
efforts.
