The Rabi oscillation accompanied by another oscillation at twice the transition frequency was analyzed when two-level atomic system was driven by strong periodic field. The number of operations of quantum bit were maximized by ratio of Rabi frequency to transition frequency which was large enough to invalidate rotating-wave approximation (RWA). The state of quantum bit depends on phase of driving field under any initial condition. This occurred due to interference of excitations caused by corotating and counteracting fields.
