    "abstract": "We suggest a scheme to generate a macroscopic superposition state\n(Schrodinger cat state) of a free-propagating optical field using a beam\nsplitter, homodyne measurement and a very small Kerr nonlinear effect. Our\nscheme makes it possible to considerably reduce the required nonlinear effect\nto generate an optical cat state using simple and efficient optical elements.",
