论文摘要
我们研究了信号光子脉冲和一维链之间的量子界面的最佳条件，该链由不同数量的原子组成。经过测试的对象是在物理上设计的，它是三脚架原子的原子阵列，该原子与纳米级介电波导限制并经历其基本HE11模式。相互作用的效率主要通过与被困原子的波导逃生场的重叠和耦合来限制。当主要散射通道内的耦合足以进一步提供各种基本界面协议，例如光存储，轻度纠缠，按需准备一些光子状态等等，我们会验证那些物理条件。
We investigate optimal conditions for the quantum interface between a signal photon pulse and one-dimensional chain consisting of a varied number of atoms. The tested object is physically designed as an atomic array of tripod-type atoms confined with a nanoscale dielectric waveguide and experiencing its fundamental HE11 mode. The efficiency of interaction is mainly limited by achieved overlap and coupling of the waveguide evanescent field with the trapped atoms. We verify those physical conditions when the coupling within the main scattering channels would be sufficient for further providing various elementary interface protocols such as light storage, light-matter entanglement, preparation of a few photon states on demand, etc.
