TRR 142 - On-demand ideal photon pair generation for entanglement swapping at telecom frequencies (C09*)
The goal of this project is the demonstration of on-demand ideal photon pair generation for entanglement swapping at telecom frequencies employing quantum dots embedded in circular Bragg grating cavities. The InAs quantum dots in an InxGayAl1-x-yAs-matrix are grown by molecular beam epitaxy and the circular Bragg grating cavity will allow to tune ...

TRR 142 - Generation and characterization of quantum light in nonlinear systems: A theoretical analysis (C10*)
We develop novel approaches based on integro-differential equations and quantum-channel descriptions for the tailored generation of nonclassical light and its propagation in structured media. By devising a multilinear process matrix formalism and accounting for complex dispersion in photonic crystals, we characterize quantum properties of light. ...

TRR 142 - Compact high performance photon pair source using ultrafast hybrid modulators based on CMOS and LNOI (C11*)
The project aims to study and demonstrate miniaturized sources of decorrelated photon pairs with high repetition rate. The goal will be achieved by jointly integrating high-bandwidth electro-optic modulators, and a specifically tailored parametric down-conversion (PDC) section, both in a lithium-niobate-on-insulator (LNOI) platform. To obtain ...

PhoQuant: Photonic Quantum Computing - Quantum computing evaluation platform
When a sufficient number of quantum particles are interconnected, quantum computers can handle tasks that are unsolvable for classical computers. This – among other unique selling points – is a major advantage of photonic platforms: Integrated architectures and sophisticated manufacturing processes offer an enormous scaling potential. The aim of ...

Photonic Quantum Systems Network (PhoQSNET) - Quantum communication infrastructure
Data security is critical to modern society. From personal data and identity fraud to cyber-attacks threatening the integrity of sovereign nations, the need for secure communication and data processing has never been greater. While quantum networks address some of these issues, in that they can be provably secure for many cryptographic ...

Covid-19 as amplifier of social inequality- SMall ARea Analyses with German neighborhood Data
In this project we seek to understand the role of disadvantaged neighborhoods with low average socio-economic status of their inhabitants. Individuals in low-income neighborhoods are often assumed to have limited possibilities to avoid contacting people infected with Sars-Cov2. This can be due to bad housing situations (e.g., more individuals live ...
