UNIQORN - Affordable Quantum Communication for Everyone - EU Quantum Flagship Project
The project "UNIQORN" (Affordable Quantum Communication for Everyone) started at the end of 2018 within the framework of the European research initiative "Quantum Flagship". The goal of the three-year project is to use photonic technologies in quantum communication. The optical systems, which currently require structures of the order of meters, ...

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 ...

ISOQC: Integrated Superconducting Optoelectronics for Quantum Communication
The aim of this project is the integration and application of high-efficiency superconducting detectors on nonlinear lithium niobate waveguides. This will enable to development of new tools in quantum optical communication technology. The main challenge is to maintain the advantages of the high nonlinearity of lithium niobate at the cryogenic ...

SPP 2111 - PONyDAC II - Precise Optical Nyquist Pulse Synthesizer DAC
Fast digital-to-analog converters (DAC) are indispensable components for modern signal processing systems. Bandwidth and effective number of bits (ENOB) are important metrics for the performance of DACs. At the same time, those parameters constitute a trade-off in the design of a DAC: The more broadband the DAC, the less typically the ENOB. This is ...

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 - 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; TP C06: Integrierte messungsinduzierte Nichtlinearitäten mit integrierten supraleitenden Detektoren
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 ...
