摘要:

我们报道了一种基于单个囚禁离子的可调谐单光子源。采用自发拉曼散射和大数值孔径的真空光学,有效地创建单光子与控制的时间形状和相干时间。这些可以在70 ns和1.6 $μ$ s之间变化,其特征在于在两个远程离子阱中同时操作两个源,这通过双光子干涉揭示了相互和个体相干性。

英文摘要:

We report a tunable single-photon source based on a single trapped ion. Employing spontaneous Raman scattering and in-vacuum optics with large numerical aperture, single photons are efficiently created with controlled temporal shape and coherence time. These can be varied between 70 ns and 1.6 $μ$s, as characterized by operating two sources simultaneously in two remote ion traps which reveals mutual and individual coherence through two-photon interference.
