Abstract
We propose a scheme to generate stationary quadripartite entanglement in two-mode optical Fabry-Perot cavity, which consisted of the same two fixed mirrors and the same two perfectly reflective movable mirrors. We treat the whole two-cavity fields-two movable mirrors system as intrinsically quadripartite and investigate quadripartite continuous-variable (CV) entanglement among them. Using the criterion proposed by Loock and Furrsawa, we demonstrate that genuine quadripartite CV entanglement can be generated in this system. This system will provide a way to create genuine quadripartite entanglement in a macroscopic level and will hold good prospects for quantum information and quantum networks.
