It is obvious from the discussion given in Chap. 2 that for a proper study of the entanglement properties of a system of more than one particle, one needs to know the density matrix of the quantum state one is interested in. For an ab-initio calculation of such a density matrix, the corresponding density operator is always required. This chapter presents useful methodologies for calculating the density operators and density matrices for the processes (1.1)–(1.8).
