论文摘要
参数驱动光腔，该光腔同时将其与原子集合量子存储器融为一体，可实现原位的多模光子 - 内存纠缠。即使在丢弃一种纠缠光学模式后，也可以生成高利率的双方光子记忆纠缠。可以使用基于与稀土离子掺杂的量子记忆集成的光子谐振器的现有技术实现此协议。与现行的量子记忆方案和实验相比，提出的方案显示出纠缠产生速率的显着优势，理论上的EBIT速率是无需微调操作条件的数十个MHz的速率。这样的光子记忆纠缠来源提供了用于量子网络和互连应用程序的多功能资源。
Parametrically driving an optical cavity that simultaneously couples to an atomic ensemble quantum memory enables in-situ generation of multimode photon-memory entanglement. A high-rate bi-party photon-memory entanglement can be generated even after discarding one entangled optical mode. This protocol can be realized with existing technologies based on photonic resonators integrated with a rare-earth-ion doped quantum memory. The proposed scheme shows significant advantages in entanglement generation rates compared with prevailing quantum memory protocols and experiments, with theoretical Ebit rates of tens of MHz without fine-tuned operating conditions. Such a photon-memory entanglement source offers a versatile resource for quantum networking and interconnect applications.
