The concept of a very true quantum computing evolves from Physics' evolution based upon quantum mechanics. We show various multiple operations through both the superposition and the phase factor connected by the phase kick-back formation, in order to store the routine of a boolean function used to compute mathematical computations in the binary system. We review the way of storing, in the quantum-gated computer, logical functions in a boolean algebra, that is developed internationally first by us. And then, we demonstrate typical arithmetic calculations in the binary system. Then we may lead to implementing commercial quantum-gated computers.
