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…
Benchmarking Gaussian and non-Gaussian input states with a hybrid sampling platform
Michael Stefszky, Kai-Hong Luo, Jan-Lucas Eickmann +22
The original boson sampling paradigm-consisting of multiple single-photon input states, a large interferometer, and multi-channel click detection-was originally proposed as a photo…
Learning to detect optical nonclassicality
Martina Jung, Suchitra Krishnaswamy, Timon Schapeler +4
Nonclassicality, defined in the quantum optical sense, serves as a resource for photon-based quantum technologies. Therefore, certifying the nonclassicality of a quantum state is c…
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…
Optimizing photon-number resolution with superconducting nanowire multi-photon detectors
Timon Schapeler, Fabian Schlue, Michael Stefszky +3
In this paper we briefly review the state-of-the-art of intrinsic photon-number resolution (PNR) with superconducting nanowire single-photon detectors (SNSPDs) and will provide an…
Jitter in photon-number-resolved detection by superconducting nanowires
Mariia Sidorova, Timon Schapeler, Alexej D. Semenov +5
By analyzing the physics of multi-photon absorption in superconducting nanowire single-photon detectors (SNSPDs), we identify physical components of jitter. From this, we formulate…
