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…
Bridging chemistry and Gaussian boson sampling: A photonic hierarchy of approximations for molecular vibronic spectra
Jan-Lucas Eickmann, Kai-Hong Luo, Mikhail Roiz +10
Simulating vibronic spectra is a central task in physical chemistry, offering insight into important properties of molecules. Recently, it has been experimentally demonstrated that…
Photorefraction Management in Lithium Niobate Waveguides: High-Temperature vs. Cryogenic Solutions
Nina A. Lange, René Pollmann, Michael Rüsing +7
Lithium niobate sees widespread use in nonlinear and quantum optical devices, such as for sum- and difference-frequency generation or spontaneous parametric down-conversion. In lit…
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…
Erasing Photon-Number Correlations through Hong-Ou-Mandel Interference
Fabian Schlue, Patrick Folge, Takefumi Nomura +6
A parametric down-conversion source interfering on a beam splitter can be described as both a source of entangled N00N-states or a source of independent, and thus uncorrelated sque…
