我们建议为为在三个远洞套住的多重原子的纠缠的状态的产生的一个计划由二相同单个模式的纤维连接了。与以前的计划相比,建议计划的明显的优点是:首先,在建议协议的所有洞能自由地与对方一起交往,它在量通讯和分布式的量计算是重要的。第二,在计划,原子,洞,和纤维,模式在回声。因此,要求的相互作用时间是短的,鉴于 decoherence,它是重要的。原则上,建议计划能被扩大产生 n 原子纠缠的状态。[从作者抽象]
An alternative scheme is proposed for engineering three-dimensional maximally entangled states for two modes of a superconducting microwave cavity. In this scheme, an appropriately prepared four-level atom is sent through a bimodal cavity. During its passing through the cavity, the atom is coupled resonantly with two cavity modes simultaneously and addressed by a classical microwave pulse tuned to the required transition. Then the atomic states are detected to collapse two modes onto a three-dimensional maximally entangled state. The scheme is different from the previous one in which two nonlocal cavities are used. A comparison between them is also made.
