TRR 142 - Three-photon state generation with on-chip pump suppression in topological waveguides (A09*)
In this project, we experimentally and theoretically study a degenerate four-wave mixing source for the generation of three-photon states, where the photons are generated inside the topological mode and propagate away from the interaction region. The design using topological protected surface modes intrinsically provides a strong suppression of the ...

TRR 142 - Cavity-enhanced spontaneous parametric down-conversion with temporal filtering using integrated superconducting detectors (C07*)
In this project, we will study the parametric down-conversion in a cavity with integrated superconducting detectors under cryogenic conditions. By using ultrafast driving electronics, we will implement pump filtering in the time domain, by enabling the integrated detector only after the pump has decayed away. The herald photon remains resonant with ...

TRR 142 - Hybrid lithium niobate on insulator quantum photonic integrated circuit (C08*)
In this project, we will explore thin-film lithium niobate on insulator (LNOI) as the material platform for quantum photonic integrated circuits. After transfer printing of cavity coupled InAs quantum dots onto a LNOI circuit, we will on-chip frequency convert the on-demand generated photons from the quantum dot using a periodically poled LNOI ...
