提出一种四模方形cluster态的制备方案，方案选用四个分别包含一个原子系综的独立单模光腔，光腔之间用短光纤实现耦合。讨论证明在合适外加激光脉冲的驱动下，可确定性的制备得到稳定的四模方形cluster态。通过调节驱动激光的频率和相位，该方案可以拓展到多模和其他形cluster态的制备。

We propose a scheme for preparation of four-mode square cluster states. We consider a chain of four single-mode cavities coupled with short fiber, each contains an atomic ensemble. We will show that a four-mode square cluster state can be deterministically prepared by driving the atomic ensembles with suitable laser pulse. The procedure can be extended to the case of multimode and other shape cluster states by choosing right frequencies and phases.
