Abstract

We analyzed the properties of superposition of light through a beam splitter and investigated the variations of the nonclassical measure and Mandel's Q-parameter. We found in the case of single input the output field possesses a reduced nonclassical measure due to the amplitude reduction through the beam splitter. In the case when two input fields are nonclassical, the output field becomes less nonclassical in a sense that the nonclassical measure (Q-parameter) of the output field is bounded below (above) a certain value subjected to the given transmittance or reflectance of the beam splitter. We also show that the nonclassical input field can be changed into a classical field as the result of superposition with thermal light.
