Macroscopic photon counting beating the Poisson noise limit
Timon Schapeler, Fabian Schlue, Isabell Mischke +4
Photon counting is a cornerstone of quantum optics. Here, we demonstrate precisely counting from 0 to over 9000 photons, beating the Poisson noise limit by at least $4.1~\mathrm{dB…

Practical considerations for assignment of photon numbers with SNSPDs
Timon Schapeler, Isabell Mischke, Fabian Schlue +4
Superconducting nanowire single-photon detectors (SNSPDs) can enable photon-number resolution (PNR) based on accurate measurements of the detector's response time to few-photon opt…
