一种偏振编码的光子-自旋界面

A Polarization Encoded Photon-to-Spin Interface

Kevin C. Chen, Eric Bersin, Dirk Englund

摘要:

我们提出了一种集成的光子器件,用于将光子偏振编码的量子比特映射到耦合到光子晶体腔的固态缺陷的自旋态上:“偏振编码光子-自旋界面”(PEPSI)。从理论上分析了态保真度与器件的偏振消光比和原子-腔协同效应的关系。此外,我们探索的速率保真度权衡通过分析和数值模型。在模拟中,我们表明,我们的设计能够实现高效,高保真的光子自旋映射。

英文摘要:

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.
