英文摘要： In this project, we study weak measurement and its applications in quantum information processing. Concretely speaking, by means of weak measurement we discuss the following questions:(1) the connections of among the information acquisition by weak measurement, the disturbance of the measured quantum system and reversibility of measurement ; (2) the realization of the new quantum feed control scheme by weak measurement; (3) the internal relations between the classic physics and quantum physics based on weak measurement technology. Through this research, we can not only enrich and develope a systematic approach based on the weak measurement technology in designing and optimizing the evolution process of quantum via weak measurement technology, but also provide valuable reference to promote the theoretical development of quantum information processing and correspongding experimental implementation.
