Quantum survival in hybrid pursuit dynamics - a lion chasing a lamb problem

P. Held, İ. Yalçınkaya, F. Pegoraro +10

Measurement and classical randomness usually degrade coherence; controlling where and when a subsystem is monitored can instead make them a tunable resource. We introduce a photoni…

An ultra-bright, highly-scalable, squeezed light source for hybrid quantum photonics

Kai-Hong Luo, Denis Kopylov, Florian Lütkewitte +8

Hybrid quantum photonics seeks to combine the complementary advantages of continuous- and discrete-variable quantum optics. This typically entails photon-counting measurements on e…

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…

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…

How well can superconducting nanowire single-photon detectors resolve photon number?

Timon Schapeler, Niklas Lamberty, Thomas Hummel +5

We apply principal component analysis (PCA) to a set of electrical output signals from a commercially available superconducting nanowire single-photon detector (SNSPD) to investiga…
