FOQUOS – Thuringian Research Group for imaging with entangled photons (started in 2018)

The aim of FOQUOS is the fundamental investigation of imaging modalities based on the peculiar properties of entangled photons. As a result, application perspectives for quantum imaging schemes and a roadmap for further development will be established.
Research is pursued along two complementary lines reflecting the strengths of the project partners in Jena and Ilmenau. First, quantum imaging schemes and the necessary photon sources will be fundamentally examined to identify conceptually new modalities, with a particular focus on making use of photon pairs with different wavelengths. Second, concepts to realize electronic components suited to implement and integrate the needed photon detection and analysis schemes will be developed. The detection of both photons should be done in real time if possible. For this purpose, ceramic-based circuit boards (LTCC) are being implemented at the IMN MacroNano® to meet these requirements. The advantage is in the realization of very short connection paths of the individual components, which enables a fast signal processing. The combination with thin-film glasses is studied to increase the degree of integration and to verify the implementation of optical components. The results of both research lines will be used to realize first demonstrators of quantum imaging schemes.

2D-SENS – Thuringian Research Group for ultrasensitive energy-efficient gas sensors from 2D materials (started in 2019)

2D-materials are ideal for nanoscale and quantum sensing applications. Consisting almost completely of surface, they interact strongly with many aspects of the environment. Their strong light-matter interaction also allows for the remote readout of their status with comparable ease. Of interest are materials of the semi-conductiong group of 2D Transition Metal Dichalcogenides (TMDs) like molybdenum disulfide (MoS2) or tungsten disulphide (WS2). Within the 2D-SENS group, we aim to use their properties specifically for gas sensors and will develop four different sensor types based on TMDs. These integrated 2D-materials will be used to investigate fundamental aspects of how the environment influences the light-matter-interaction in 2D-materials, regarding fluorescence lifetimes, spectra and valley-excitonic properties.

FASTPHOTON – Thuringian Research Group for single-photon laser-diodes in quantum communication (started 2020)

Quantum physical phenomena enable novel applications in science and technology that lead to significant improvements in information processing. In particular, quantum communication is already technologically mature for real application scenarios. By means of Quantum Key Distribution (QKD), it is possible to drastically increase data security in new digital business fields such as smart grids, personalized medicine or microtransaction banking. Thus, quantum-based, secure communication can become the locational advantage of a data-driven economy. However and so far, many quantum communication scenarios achieve only low electro-optical integration density and key rates in the low kbit range. The overall goal of our research group FastPhoton is to advance quantum communication by focussing on the high-frequency control of photon sources in high-performance opto-electronic components and assemblies. We are targeting applications of optical, quantum-based data communication in fiber optical and and satellite networks.
