<p><em>Photon-number resolution is crucial in various quantum systems, including quantum computation and communication. Superconducting nanostrip single-photon detectors (SNSPDs) are prominent in single-photon detection but face challenges in photon-number resolution fidelity and dynamic range. Researchers from the Shanghai Institute of Microsystem and Information Technology (SIMIT), Chinese Academy of Sciences, have made significant progress by widening superconducting strips. This innovation, detailed in Advanced Photonics, enables true-photon-number resolution up to 10 with the superconducting microstrip single-photon detector (SMSPD), achieving remarkable readout fidelity without cryogenic amplifiers. Additionally, a proposed dual-channel timing setup simplifies real-time photon-number readout. This advancement promises broader applications in optical quantum information fields, with implications for high-fidelity photon-number resolution.</em></p>
