Recently, Kai Zou and others' paper was published by Physical Review Applied. The title of the paper is "Superconducting nanowire photon-number-resolving detectors integrated with current reservoirs". In this paper, we proposed one type of photon-number-resolving detectors based on superconducting nanowires especially integrated with current reservoirs. The information about the detected photon number is stored in the format of the supercurrent in the current reservoir.
