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 ...

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 ...
