摘要
基于多次穿过的马赫-曾德尔干涉仪,采用双通道压缩和双输出组合测量进行相位测量,对比了单端测量、差分测量和双输出组合测量的特点.结果表明,采用双通道压缩和双输出组合测量,能大幅度提高相位测量精度,可打破标准量子极限.
Abstract
This paper introduces the phase measurement based on multi-pass Mach-Zehnder interferometer,which adopts two-channel compression and two-output combination measurement,and explains the single-end measurement,differential measurement and double-output combination measurement.It is shown that,the phase measurement accuracy can be greatly improved and the standard quantum limit can be broken by using the combination of two-channel compression and two-output measurement.
