论文摘要
我们证明了基于量子检测器断层扫描的不同多路复用体系结构的比较。利用其测量结果的纯度，我们可以洞悉设备的光子单位分辨能力。此外，我们计算每个测量结果可以在给定维度的希尔伯特空间中提取出来的信息。我们的工作证实，更多的多重结果可以促进更高的光子数分辨率。但是，这些结果之间的分裂也必须优化。
We demonstrate a comparison of different multiplexing architectures based on quantum detector tomography. Using the purity of their measurement outcomes, we gain insight about the photon-number resolving power of the devices. Further, we calculate the information each measurement outcome can extract out of a Hilbert space with given dimension. Our work confirms that more multiplexing outcomes enable higher photon-number resolving power; however, the splitting between those outcomes must be optimized as well.
