Projects
The PhoQS is characterised by its interdisciplinary structure and the close cooperation of numerous specialised working groups. This diversity makes it possible to work on projects from a wide range of research and application fields. The focus is on innovative approaches that combine basic research and applied sciences.
Depending on the issue and objective, PhoQS integrates expertise from the fields of physics, electrical engineering, computer science and mathematics in order to tackle complex challenges and develop new solutions.

Festkörperbasierte Schlüsselbauelemente für die Quantenkommunikation / Q.link.X - Quantenrepeater für eine abhörsichere Kommunikation über große Distanzen
In the course of the digitalization of our society, data security and secure communication are becoming increasingly important. Quantum communication offers a promising approach for a fundamental solution to the security issues at hand: It uses quantum states as information carriers that cannot be cloned or read unnoticed due to fundamental ...

TRR 142 - Nonlinear coupling of interlayer excitons in van der Waals heterostructures to plasmonic and dielectric nanocavities (A08)
The main focus of project A08 is on interlayer excitons trapped in the controllable superlattices that naturally arise in Moiré patterns. We will study the behavior of interlayer excitons as single-photon emitters, and how it is influenced by their quantum confinement and by the orientation of their electric dipole. Then, we will explore strategies ...

TRR 142 - Tailored KTP and LiNbO3 waveguide structures for counter-propagating parametric down-conversion processes (B05)
This project aims at the fabrication of periodically poled waveguide structures with ultrashort periods in lithium niobate and KTP for counter-propagating parametric down conversion. We will focus on the development of the technological processes required to achieve ultra short domain periods in a combined technological and analytical approach in ...

TRR 142 - Integrierte messungsinduzierte Nichtlinearitäten mit integrierten supraleitenden Detektoren (C06)
This project will investigate the theoretical potential and experimental feasibility of integrating superconducting nanowire single-photon detectors (SNSPDs) on lithium niobate waveguides in order to implement a measurement-induced nonlinearity. Such nonlinearities arise from probabilistic mea-surement events and as such, can be implemented at very ...

Integrierte Quantenlicht-Quellen für Systeme kontinuierlicher Variablen
Die integrierte Optik ermöglicht die Realisierung komplexer optischer Strukturen auf monolithischen nicht-linearen Wellenleiterstrukturen. Damit können erstmals miniaturisierte Quantenlicht-Quellen und Multiplexaufbauten mit verschiedenen Funktionalitäten und maßgeschneiderten Eigenschaften realisiert werden, die in üblichen Freistrahlaufbauten ...

Nichtlineares Charakterisierungssystem
Die Beantragung eines nichtlinearen Charakterisierungssystems am Lehrstuhl für Angewandte Physik / Integrierte Quantenoptik dient als Bindeglied zwischen der Probenherstellung (Technologie) und der quantenoptischen Anwendung (Optiklabor). Die Forschung setzt im Kern auf periodisch gepolte Wellenleiter in nichtlinearen Kristallen, die spezifische ...
