abstract="The use of improved fabrication technology, highly disordered NbN thin films, and intertwined section topology makes it possible to create high-performance photon-number-resolving superconducting single-photon detectors (PNR SSPDs) that are comparable to conventional single-element SSPDs at the telecom range. The developed four-section PNR SSPD has simultaneously an 86{\textpm}3{\%} system detection efficiency, 35 cps dark count rate, \~{}2{\thinspace}ns dead time, and maximum 90 ps jitter. An investigation of the PNR SSPD{\textquoteright}s detection efficiency for multiphoton events shows good uniformity across sections. As a result, such a PNR SSPD is a good candidate for retrieving the photon statistics for light sources and quantum key distribution systems.",
