The atom-field interaction can be controlled by amplitude, frequency or phase of a coherent field. Here we shine an amplitude and phase modulated microwave pulse onto a superconducting artificial atom in a semi-infinite one-dimensional transmission line. Specifically, we launched a weak exponential rising pulse to the qubit to achieve maximal loading efficiency of 94.5% and we showed that the interaction can be tuned from full interaction to effectively no interaction (3.5% loading efficiency) by simply change the modulation phase.
