论文摘要
我们提出了一个集成的光子设备，用于将光子极化编码的量子位映射到固态缺陷的旋转状态上，该固态缺陷耦合到光子晶体腔：“偏振编码的光子到旋转旋转界面”（百事可乐）（PEPSI）。我们对状态保真度对设备的极化灭绝比和原子腔合作的依赖性进行了理论分析。此外，我们通过分析和数值模型探索了速率的权衡权衡。在模拟中，我们表明我们的设计实现了有效的高保真光子到旋转映射。
We propose an integrated photonics device for mapping qubits encoded in the polarization of a photon onto the spin state of a solid-state defect coupled to a photonic crystal cavity: a `Polarization-Encoded Photon-to-Spin Interface' (PEPSI). We perform a theoretical analysis of the state fidelity's dependence on the device's polarization extinction ratio and atom-cavity cooperativity. Furthermore, we explore the rate-fidelity trade-off through analytical and numerical models. In simulation, we show that our design enables efficient, high fidelity photon-to-spin mapping.
