论文摘要
有效网络节点的开发是实现量子网络的关键要素，量子网络有望作为分布式量子计算或可证明的安全通信。我们使用基于纤维的Fabry-Perot腔中的被困离子来报告量子网络节点的实现。我们以高保真度为$ 91.2（2）$ \，\％的确定性纠缠的产生，在被困的Yb-ion和发射到谐振器模式中的光子之间。我们获得了$ 2.5 \ cdot 10^{ - 3} $的单镜头生成和检测纠缠的成功概率，导致62 \，Hz纠缠率。
The development of efficient network nodes is a key element for the realisation of quantum networks which promise great capabilities as distributed quantum computing or provable secure communication. We report the realisation of a quantum network node using a trapped ion inside a fiber-based Fabry-Perot cavity. We show the generation of deterministic entanglement at a high fidelity of $ 91.2(2) $\,\% between a trapped Yb--ion and a photon emitted into the resonator mode. We achieve a success probability for generation and detection of entanglement for a single shot of $ 2.5 \cdot 10^{-3}$ resulting in 62\,Hz entanglement rate.
