论文摘要
我们提出了一种计划，以生成连续变量（CV）多部分纠缠状态，使用一系列血浆石墨烯波导阵列被非经典驾驶微波模式激活。在此方案中，我们可以利用在每个波导中耦合到同一微波模式的两个光场的相互作用，以产生任何类型的多部分高斯纠缠状态。使用结果CV多部分纠缠状态说明了传送网络。特别是，所提出的设置使跨远程连接的节点具有相干状态传送，其保真度高于阈值限制，即使在存在损失的情况下，也可以提供安全的量子传送网络。
We present a scheme to generate a continuous variable (CV) multipartite entangled state using an array of plasmonic graphene waveguides that are activated by nonclassical driving microwave modes. Within this scheme, we can exploit the interaction of two light fields coupled to the same microwave mode in each waveguide to produce any type of multipartite Gaussian entangled state. A teleportation network is illustrated using the resultant CV multipartite entangled state. In particular, the proposed setup enables coherent state teleportation across remotely connected nodes with fidelity above a threshold limit of 2/3, providing secure quantum teleportation networking even in the presence of losses.
