  bibo_abstract:
  - <jats:p>Superconducting nanowire single-photon detectors (SNSPDs) can enable photon-number
    resolution (PNR) based on accurate measurements of the detector’s response time
    to few-photon optical pulses. In this work, we investigate the impact of the optical
    pulse shape and duration on the accuracy of this method. We find that Gaussian
    temporal pulse shapes yield cleaner arrival-time histograms and, thus, more accurate
    PNR, compared to bandpass-filtered pulses of equal bandwidth. For low system jitter
    and an optical pulse duration comparable to the other jitter contributions, photon
    numbers can be discriminated in our system with a commercial SNSPD. At 60 ps optical
    pulse duration, photon-number discrimination is significantly reduced. Furthermore,
    we highlight the importance of using the correct arrival-time histogram model
    when analyzing photon-number assignment. Using exponentially modified Gaussian
    distributions, instead of the commonly used Gaussian distributions, we can more
    accurately determine photon-number misidentification probabilities. Finally, we
    reconstruct the positive operator-valued measures of the detector, revealing sharp
    features that indicate the intrinsic PNR capabilities.</jats:p>@eng
