Quantum detector tomography of high-dimensional multiplexed superconducting detectors

Your library or personal account may give you access

Abstract

We demonstrate quantum detector tomography of three different multiplexed SNSPDs, including a nonlinear detector of dimension > 103. We use this to extract efficiency, dark-count and cross-talk probability from just four elements of the reconstructed POVMs.
