A robust framework for the comprehensive characterisation of parametric down-conversion sources
Denis A. Kopylov, Michael Stefszky, Christine Silberhorn
Reliable verification of squeezed-light sources is essential for photonic quantum technologies. High-dimensional quantum optical networks demand single-mode, pure squeezed states w…
Pathway-resolved analysis of internal conversion enabled by Gaussian boson sampling
Mikhail Roiz, Rashid Valiev, Jan-Lucas Eickmann +4
Gaussian Boson Sampling (GBS) has provided strong evidence of quantum advantage, motivating the search for real-world applications. Such applications rely on mapping physical probl…
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…
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…
