摘要: 本文对《大学物理》论文“关于拉比强信号理论的疑问和思考解答”中讨论的问题进行了重新讨论,其理论推导更简洁,物理解释更准确. 通过本文我们再次强调,在量子理论中,描述状态的不是概率,而是概率幅. 概率相同的状态,概率幅可以不同,从而状态不同.

关键词: 量子光学, 原子与电磁场相互作用, 概率幅, 概率

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
