Abstract: In the course of quantum mechanics, the state superposition principle plays a key role of the overall situation. Also, it is a difficult content in the teaching process. We introduce the teaching experience about quan- tum state superposition principle in this paper. After lecturing the principle of quantum state superposition with a typical problems solving process, we explain how to correctly compute mechanics operators in quantum superposi- tion state and discuss the relationship of observation and measurement value. It is helpful to understand the wave function collapse, correct understanding of the quantum state not cloning theorem and the empty preach content the- ory.

Key words: superposing states, quantum measurement, operator image, state collapse
