    "abstract": "We demonstrate the surprising integrability of the classical Hamiltonian\nassociated to a spin 1/2 system under periodic external fields. The one-qubit\nrotations generated by the dynamical evolution is, on the one hand, close to\nthat of the rotating wave approximation (RWA), on the other hand to two\ndifferent ``average\u0027\u0027 systems, according to whether a certain parameter is\nsmall or large. Of particular independent interest is the fact that both the\nRWA and the averaging theorem are seen to hold well beyond their expected\nregion of validity. Finally we determine conditions for the realization of the\nquantum NOT operation by means of classical stroboscopic maps.",
