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…
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…
Cryogenic Feedforward of a Photonic Quantum State
Frederik Thiele, Niklas Lamberty, Thomas Hummel +8
Modulation conditioned on measurements on entangled photonic quantum states is a cornerstone technology of optical quantum information processing. Performing this task with low lat…
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…
Cryogenic integrated spontaneous parametric down-conversion
Nina Amelie Lange, Jan Philipp Höpker, Raimund Ricken +4
Scalable quantum photonics relies on interfacing many optical components under mutually compatible operating conditions. To that end, we demonstrate that spontaneous parametric dow…
