AI 中文摘要
我们提出一种里德伯量子天线，由驻波光镊中捕获的一维中性原子链构成，用作芯片接口的单光子源。里德伯阻塞在原子链中诱导单个集体激发，而其有序几何结构将光子发射塑造成定向光束，从而实现严格每次只发射一个光子的量子天线。通过数值模拟，我们展示了经高数值孔径透镜进入波导的单光子收集效率超过70%，且多重激发概率可忽略不计。这些性能对驻波偶极阱中的概率性原子装载具有鲁棒性，仅需十个原子即可实现，表明实验可行性。因此，里德伯量子天线为可扩展的高效率、高纯度且一致的单光子源阵列与光子芯片接口提供了一条独特途径，解决了光子量子信息技术中的关键挑战。
英文摘要
We propose a Rydberg quantum antenna, consisting of a one-dimensional chain of neutral atoms trapped in a standing-wave optical tweezer, as a chip-interfaced single-photon source. Rydberg blockade induces a single collective excitation in the atomic chain, while its ordered geometry shapes the photon emission into a directional beam, thereby realizing a quantum antenna that emits strictly one photon at a time. Through numerical simulations, we demonstrate single-photon collection efficiencies into a waveguide exceeding 70\% through a high-NA lens with a negligible multiple excitation probability. These performance are robust against probabilistic atom loading in the standing-wave dipole traps, requiring only ten atoms, indicating experimental feasibility. The Rydberg quantum antenna thus offers a unique route toward scalable arrays of high-efficiency, high-purity, and identical single-photon sources interfaced with a photonic chip, addressing key challenges in photonic quantum information technology.
