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…
