Widely non-degenerate nonlinear frequency conversion in cryogenic titanium in-diffused lithium niobate waveguides
Nina Amelie Lange, Sebastian Lengeling, Philipp Mues +6
The titanium in-diffused lithium niobate waveguide platform is well-established for reliable prototyping and packaging of many quantum photonic components at room temperature. Neve…
Indefinite causal order in cavity quantum electrodynamics
Lorenzo M. Procopio, L. O. Castaños-Cervantes, Tim J. Bartley
Indefinite causal order (ICO) has the potential to be a new resource for quantum information processing. In most of its experiments, ICO has been investigated in a photonic platfor…
Harnessing of temporal dispersion for integrated pump filtering in spontaneous heralded single-photon generation processes
Julian Brockmeier, Timon Schapeler, Nina Amelie Lange +4
Cointegration of heralded single-photon generation and on-chip detection requires the ability to differentiate between pump light and single photons. We explored the dispersion-ind…
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…
Low-noise Balanced Homodyne Detection with Superconducting Nanowire Single-Photon Detectors
Maximilian Protte, Timon Schapeler, Jan Sperling +1
Superconducting nanowire single-photon detectors (SNSPDs) have been widely used to study the discrete nature of quantum states of light in the form of photon-counting experiments.…
Degenerate Photons from a Cryogenic Spontaneous Parametric Down-Conversion Source
Nina Amelie Lange, Timon Schapeler, Jan Philipp Höpker +2
We demonstrate the generation of degenerate photon pairs from spontaneous parametric down-conversion in titanium in-diffused waveguides in lithium niobate at cryogenic temperatures…
