From this, we formulate a quantitative physical model of the multi-photon detector response that combines the local detection mechanism and local fluctuations (hotspot formation and intrinsic jitter) with the thermoelectric dynamics of resistive domains. Our model provides an excellent description of the arrival-time histogram of a commercial SNSPD across several orders of magnitude, both in arrival-time probability and across mean photon number. This is achieved with just three fitting parameters: the scaling of the mean arrival time of voltage response pulses, as well as the Gaussian and exponential jitter components. Our findings have important implications for photon-number-resolving detector design, as well as applications requiring low jitter, such as light detection and ranging (LIDAR).</jats:p> AIP Publishing2025 eng JitterPNRSNSPD 2378-0967 arXiv:2503.1714610.1063/5.0273752 108 Sidorova, Mariia, et al. “Jitter in Photon-Number-Resolved Detection by Superconducting Nanowires.” <i>APL Photonics</i>, vol. 10, no. 8, 086113, AIP Publishing, 2025, doi:<a href="https://doi.org/10.1063/5.0273752">10.1063/5.0273752</a>. @article{Sidorova_Schapeler_Semenov_Schlue_Stefszky_Brecht_Silberhorn_Bartley_2025, title={Jitter in photon-number-resolved detection by superconducting nanowires}, volume={10}, DOI={<a href="https://doi.org/10.1063/5.0273752">10.1063/5.0273752</a>}, number={8086113}, journal={APL Photonics}, publisher={AIP Publishing}, author={Sidorova, Mariia and Schapeler, Timon and Semenov, Alexej D. and Schlue, Fabian and Stefszky, Michael and Brecht, Benjamin and Silberhorn, Christine and Bartley, Tim}, year={2025} } Sidorova M, Schapeler T, Semenov AD, et al.
