基于相干态指针实现光机械系统中的弱测量放大

Realization of Weak Measurement Amplification in Opto-Mechanical System based on Coherent State Pointer

为理解相干态指针在光机械系统中进行正交后选择弱测量导致镜子位移的放大效果,本文引入了一种新的有关放大的物理机制,同时提出了满足这种放大机制的光机械系统方案,对光机械系统在量子通讯、量子传感、量子计算的应用具有一定的指导作用。

In order to understand the magnifying effect of the mirror displacement caused by the weak measurement of the coherent state pointer after being orthogonal in the opto-mechanical system,a new physical mechanism of am⁃plification is imported,and at the same time,an opto-mechanical system scheme satisfying this amplification mecha⁃nism is proposed,which plays a guiding role in the application of opto-mechanical system in quantum communica⁃tion,quantum sensing and quantum computing.
