标题： Hybrid entanglement of three quantum memories with three photons

摘要： 量子网络在实际和基本应用方面都有重要意义。 具有光子和静态节点的混合架构前景广阔。 到目前为止，实验实现仅限于两个节点和两个光子。 通过将许多光子与许多量子节点纠缠，超越现有技术水平备受期待。 在此，我们报告了一个实验，实现了三个光子与三个原子系综量子存储器之间的混合纠缠。 我们使用了三个相似的装置，在每个装置中，通过腔增强，创建了一对具有高总体效率的光子-存储器纠缠。 通过三光子干涉，三个量子存储器与三个光子纠缠。 通过测量光子并应用前馈，我们成功地纠缠了三个存储器。 我们的工作展示了最大规模的混合存储器-光子纠缠，这可能被用作构建更大更复杂量子网络的构建模块。 显示英文摘要

摘要： Quantum network has significant applications both practically and fundamentally. A hybrid architecture with photons and stationary nodes is highly promising. So far, experimental realizations are limited to two nodes with two photons. Going beyond state of the art by entangling many photons with many quantum nodes is highly appreciated. Here, we report an experiment realizing hybrid entanglement between three photons and three atomic-ensemble quantum memories. We make use of three similar setups, in each of which one pair of photon-memory entanglement with high overall efficiency is created via cavity enhancement. Through three-photon interference, the three quantum memories get entangled with the three photons. Via measuring the photons and applying feedforward, we heraldedly entangle the three memories. Our work demonstrates the largest size of hybrid memory-photon entanglement, which may be employed as a build block to construct larger and complex quantum network.
