Abstract
Sub-shot-noise measurement for slight absorption is experimentally ach ieved with the twin beams of quantum correlation. The improvement in s ignal-to-noise ratio of 2.5 dB relative to the SNL is obtained. The ex perimental results demonstrate the predictions of the semi-classical t heory.
