摘要

The present disclosure provides a method and system for improving a counting rate of a superconducting nanowire single photon detector. The method includes: coupling an electrical attenuator in series with an output end of the superconducting nanowire single photon detector; the electrical attenuator includes an input end and an output end, and the input end of the electrical attenuator is coupled with the output end of the superconducting nanowire single photon detector. The present disclosure couples the electrical attenuator in series with the output end of the superconducting nanowire single photon detector. Since the configuration of the electrical attenuator is a resistor network, it can act as a series resistor and can also reduce the response pulse amplitude of the superconducting nanowire single photon detector. The present disclosure can improve the counting rate of the superconducting nanowire single photon detector, while keeping the detection efficiency high.
