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…
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…
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…
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…
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…
Spectral and temporal properties of type-II parametric down-conversion: The impact of losses during state generation
Denis A. Kopylov, Michael Stefszky, Torsten Meier +2
In this paper, we theoretically study spectral and temporal properties of pulsed spontaneous parametric down-conversion (SPDC) generated in lossy waveguides. Our theoretical approa…
