Resolving Photon Numbers Using Ultra-High-Resolution Timing of a Single Conventional Superconducting Nanowire Detector
Gregor Sauer, Mirco Kolarczik, Rodrigo Gómez, Helmut Fedder, Fabian Steinlechner · 2023
We show how ultra-high-resolution timing measurements of the rising and falling edges of electrical pulses generated from conventional superconducting nanowire detectors enable to distinguish photon numbers of up to 5 in a single-shot measurement.
