在最近的量子光学连续变量实验中，通过在时域或频域中引入复用方案，完全不可分离的光模式的数量急剧增加。在这里，修改了 Yokoyama 等人的工作中报告的时域复用实验。 [纳特。 Photonics 7, 982 (2013)]，我们展示了超过一百万种完全不可分离的光模式的连续生成。由此产生的多模式状态可用作双轨连续变量集群状态。我们通过光学系统的连续反馈控制，规避了之前的光学相位漂移问题，该问题将完全不可分离的光模式的数量限制在一万左右。
In recent quantum optical continuous-variable experiments, the number of fully inseparable light modes has drastically increased by introducing a multiplexing scheme either in the time domain or in the frequency domain. Here, modifying the time-domain multiplexing experiment reported in the work of Yokoyama et al. [Nat. Photonics 7, 982 (2013)], we demonstrate the successive generation of fully inseparable light modes for more than one million modes. The resulting multi-mode state is useful as a dual-rail continuous variable cluster state. We circumvent the previous problem of optical phase drifts, which has limited the number of fully inseparable light modes to around ten thousands, by continuous feedback control of the optical system.
