Description:
Author(s): Xuanmin Zhu, Yuxiang Zhang, Quanhui Liu, and Shengjun Wu We investigate the relationship between the information gain and the interaction strength between the quantum system and the measuring device. A strategy is proposed to calculate the information gain of the measuring device as a function of the coupling strength. For qubit systems, we prove that the... [Phys. Rev.
