Abstract
Abstract
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.
