  This paper deduces universal uncertainty principle in different quantum
theories after about one century of proposing uncertainty principle by
Heisenberg, i.e., new universal uncertainty principle of any orders of physical
quantities in quantum physics, overcomes the difficulty that current quantum
computer, quantum communication, quantum control, quantum mechanics and so on
theories cannot give exact values of general uncertainty of any orders of
physical quantities, further gives all relevant different expressions of the
universal uncertainty principle and their applications. In fact, our studies
are consistent with current theories and physical factual experiments, e.g.,
relevant to hydrogen atom physics experiments. Using the new universal
uncertainty principle, people can give all applications to atomic physics,
quantum mechanics, quantum communication, quantum calculations, quantum
computer and so on.
