| 摘 要： | 利用金刚石氮空位色心体系耦合于一个双边的光子晶体腔(该光子晶体腔与两个波导耦合)来制备Bell态、GHZ态和团簇态。当光子被探测和进行幺正操作后,就得到纠缠态。同时计算了该体系的保真度,发现在近似参数条件下,该模型可得到较好结果。

| Abstract: | We propose theoretical schemes to generate Bell state,GHZ state and cluster state with the help of a diamond nitrogen-vacancy color center embedded in a photonic crystal cavity coupled to two waveguides.With single-photon detection and local unitary operation,these entangled states could be generated.The fidelities of our schemes are also calculated,which illustrate that our schemes have a good performance under appropriate parameter conditions. |
