Abstract：
This paper studies quantum correlations of quantum systems and the basic dynamics process, which initiates the forming of quantum correlations. It discusses the mutual contact between the emergence of the condensate and the formation of off-diagonal long-range order. It discusses the one-particle density matrix as a primary object displaying such an order. And it derives an expression for the cross section of the direct and the reversed processes in the lowest order. Accordingly, important information about quantum correlations can be deduced directly from the differential scattering cross section of these processes.
