Variation of nonclassical states of light

초록

We consider a beam splitter as an optical device to generate a class of nonclassical states out of a nonclassical input state. On sending a nonclassical light toward one input port and the vacuum to the other, one can generally obtain the two output lights which are less nonclassical than the input state. We also consider the limit, in which the input intensity grows indefinitely and the trasmission coefficient vanishes such that their product becomes finite, to find various states of light lying between nonclassical and classical states.
