INQUOSENS - THURINGIAN INNOVATION CENTER FOR QUANTUM OPTICS AND SENSING

InQuoSens brings together excellent and internationally visible research activities of ACP and the Institute for Micro- and Nanotechnologies at the Technical University of Ilmenau (IMN) in the key technologies quantum optics and sensor technology. By means of strategic investments measures and a joint strategy process at both locations, these fields are synergistically developed. InQuoSens coordinates its scientific development with the innovative needs of the Thuringian metrology and communication industry. For example, and together with the Fraunhofer IOF, InQuoSens is currently working on the question of how quantum technologies can be used in autonomous driving or medical diagnostics. Through these activities, InquoSens will develop into an internationally independent center of scientific excellence with a critical mass of competences, which will increase the innovative power of the Thuringian economy. InQuoSens is supported by the State of Thuringia with EUR 3.0 million from 2017 until 2022.

Prototyping Infrastructure

ACP_InQuoSens_NanoLab_web350The preparation of micro- and nanostructured optical devices for the integration into quantum optical systems and for the quantum optical characterization requires an elaborate technological processing. Within InQuoSens, nanostructured functionalized surfaces up to atomic membrane systems are considered as particularly promising fields of technology for the realization of efficient quantum optical devices. Therefore, prototyping technologies for these material systems are highly relevant and existing coating and structuring technologies shall be supplemented by missing technology steps.

Device Characterization Infrastructure

Imaging quantum detectors: Quantum imaging technologies are an essential part of the InQuoSens technology roadmap. The Thuringian industry has traditionally a strong focus on imaging optical systems. These systems shall be advanced to single-photon sensitive methods and suitable quantum-optical evaluation protocols, e.g. ghost imaging techniques, shall be developed.

InQuoSens_Quantum_web350Quantum-optical characterization setup for the MIR spectral region: Due to the characteristic molecular-specific optical properties of substances in the mid-infrared spectral region (MIR), sensor systems and imaging techniques in this spectral region have a high potential for research and development especially in the material and life sciences. Up to now, this potential cannot be fully exploited as technological challenges regarding spectroscopic characterization systems in this spectral region and hyperspectral imaging methods have not yet been solved completely. This holds true especially for spectroscopy and imaging on the single-photon level using quantum-mechanical correlations. InQuoSens is dedicated to this problem and will investigate quantum optical sensor and imaging systems in this spectral range.

Components for a correlated ohoton source in the UV spectral region: The spatial resolution of imaging sensors is bounded by the Abbe limit and is directly related to the wavelength of the detected photons. For this reason, there have been long standing efforts to scale existing imaging methods to shorter wavelengths. Recently, great progress has been made due to the improved availability of laser sources in the ultraviolet (UV) and extreme ultraviolet (XUV) spectral region. Yet, it has been shown that, in particular, the application of these imaging methods in the life sciences is severely hindered by the intense light-matter interaction of the high-energy photons. Even the smallest photon doses cause significant damage to biological samples. Therefore, detection methods that work with very low photon fluxes are of utmost importance, which will be addressed within InQuoSens by the development of quantum-optical sensor technologies and imaging methods in the mentioned spectral regions.
