Abstract

We present the first experimental evidence of photon number resolution in a conventional superconducting nanowire single-photon detector. The photon-number-dependent resistance reflected in the rise-time of output pulses is detected using a wideband, low-noise read-out circuit.

Many quantum applications will benefit significantly from photon number resolving detection. However, photon number resolving detectors have been largely experimental devices implemented in laboratory settings. Recent advances in superconducting nanowire device fabrication and readout techniques have enabled the implementation of photon number resolution in widely deployable commercial single-photon detection systems. We will discuss progress in implementing photon number resolved detection with commercially produced superconducting nanowire single photon detectors via spatial multiplexing of independently instrumented detector elements and photon number dependent rise-time changes in single-element nanowire devices.
