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 ...
