摘要

我们研究了基于连续时间复用技术的光子数量分辨探测器的特性。我们建立并验证了这种探测器的数学模型，并探索了其量子层析成像的各种方法。此外，我们还遇到了记忆效应，并讨论了使用转移矩阵或正算子值量（POVM）分解来描述这种探测器的可行性。

Quantum tomography of a photon-number-resolving detector based on continuous time multiplexing: memory effect

We address the characterization of a photon-number-resolving detector based on continuous time multiplexing. We develop and verify a mathematical model of this detector and explore various approaches to its quantum tomography. Additionally, we encounter a memory effect and discuss the feasibility of describing this type of detector using a transfer matrix or positive operator-valued measure (POVM) decomposition.
