论文摘要
我们从理论上研究泵的亮度如何具有固定轮廓，影响由固定参数波导源产生的挤压状态的时间模式结构。我们发现，这些挤压状态的时间模式可能部分不匹配，因此可以区分，这在使用这些状态作为量子计算或宣传状态的资源时是不希望的。通过研究使用实验的常见频率过滤技术，我们发现，尽管可以恢复没有可区分的性能，但它以可能会大大降低国家纯度的代价。我们考虑三种不同的源配置：未封闭的单个通行证，抛光的单个通行证和抛光的双通道。我们发现，双通配置在不同程度的亮度上产生几乎无法区分的状态的最佳结果。
We study theoretically how the brightness of pumps, with fixed profiles, affects the temporal mode structure of squeezed states generated by fixed parametric waveguided sources. We find that the temporal modes of these squeezed states can be partially mismatched and thus distinguishable, which is undesirable when using these states as resources for quantum computing or heralded state generation. By studying common frequency filtering techniques used experimentally, we find that although one can regain indistinguishability it comes at the price of potentially greatly reducing the purity of the state. We consider three different source configurations: unapodized single pass, apodized single pass, and apodized double pass. We find that the double pass configuration produces optimal results with almost perfectly indistinguishable states over varying degrees of brightness.
