The paper attempts to explain how the result of quantum mechanics is the natural obstacle to the existing computer technology--10 10 m is the limit of the integration of the fuse slice.
The paper attempts to explain, from the principle of quantum mechanics , the result of quantum mechanics is the natural obstacle to the existing computer technology--10 10 m is the limit of the integration of the fuse slice. The reason is also discussed why quantum computers have powerful computation ability --the related effect of the quantum entanglement. Some possible plans of the quantum computers are proposed. It is pointed out that microphyics and the existing technology of computers should be combined in the research of quantum computers.
