Abstract: The problem in the paper titled “questions and reflections on Rabi’s signal theory” in College Physics is re-discussed. Our theoretical deduction is more concise, and our physics explanation is clearer. We emphasize once more that the quantum states are described  by probability amplitudes, not by probabilities. The states with a same probability can have different probability amplitudes, so they are different states.

Key words: quantum optics, interaction between atom and field, probability amplitude, probability
