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.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
