The colour of light entails rich information even at the single-photon level. However, frequency-resolving single-photon detectors that simultaneously feature high detection efficiency and low timing jitter remain elusive. In this paper, the authors propose a nanoscale architecture for single-photon detectors to bridge the gap, opening a promising avenue toward a plethora of sensing and imaging applications.
