Monte-Carlo-Markov-Chain Detector Tomography of Nanobridge SNSPDs with 56% Quantum Efficiency
Superconducting Nanowire Single Photon Detectors (SNSPDs) are a leading technology for quantum optics and information, offering fast recovery, low timing jitter, high detection efficiency, and intrinsic photon number resolution, making them ideal for future quantum applications [1]. We introduce a Monte-Carlo-Markov-Chain (MCMC) approach to Detector Tomography for nanobridge NbTiN devices, separating internal and external quantum efficiencies. This is key to understanding SNSPD detection mechanisms and performance trade-offs.
