摘要:

我们研究了微波频率梳模式内的非互易散射。通过调节 Josephson 参量振荡器的泵浦频率、振幅和相位,我们控制了 $m \longrightarrow \ell$ 散射过程的相长干涉,同时实现了逆过程 $\ell \longrightarrow m$ 的相消干涉。我们概述了在双模隔离和三模环流背景下实现非互易性的方法,并将其扩展到多模。实验与线性化理论模型吻合良好。非互易散射扩展了参量控制的工具集,有望用于构建替代的量子关联。

英文摘要:

We investigate nonreciprocal scattering within the modes of a microwave frequency comb. Adjusting the pump frequencies, amplitudes, and phases of a Josephson parametric oscillator, we control constructive interference for the $m \longrightarrow \ell$ scattering processes, while concurrently achieving destructive interference for the inverse process $\ell \longrightarrow m$. We outline the methodology for realizing nonreciprocity in the context of two-mode isolation and a three-mode circulation, which we extend to multiple modes. We find good agreement between the experiments and a linearized theoretical model. Nonreciprocal scattering expands the toolset for parametric control, with the potential to engineer alternative quantum correlations.
