| Abstract: | It is described how a quantum system composed of a cavity field interacting with a movable mirror can be utilized to generate a superposition of Fock states of the cavity field by measuring the position coordinate of the mirror.Then the squeezing and coherence properties of the cavity are discussed.By using numerical calculation,it is found the cavity has some nonclassical properties.It shows squeezing effect and antibunching effect. |

| Keywords: | Cavity Moving mirror Superposition of Fock states Squeezing effect Antibunching effect |
