摘要：A kind of new operators, the generalized pseudo-spin operators are introduced and a universal intrinsic Hamiltonian of two-qubit interaction is studied in terms of the generalized pseudo-spin operators. A fundamental quantum gate U(theta) is constructed based on the universal Hamiltonian and shown that the roles of the new quantum gate U(theta) is equivalent, functionally, to the joint operation of Hadamard and C-Not gates.
