Fraunhofer Institute for Applied Optics and Precision Engineering IOF
The Fraunhofer-Institute of Applied Optics and Precision Engineering IOF sees itself as part of the scientific and technical spirit of its namesake and of the found fathers of the photonics cluster in Jena as well. It aims to combine scientific excellence in the generation, control, and manipulation of light with innovative application development at the highest level in order to generate solution with and for light.
The Fraunhofer IOF is a pioneer in the field of applied research for optical quantum technologies and offers innovative solutions for applications in science and industry where quantum-technological systems have the potential to enable revolutionary applications, e.g., reliable quantum communication, low-noise quantum imaging, and advanced ion traps for quantum computers. For this purpose, optical systems are integrated, miniaturized, and optimized, whereby the competencies of the institute cover the entire quantum photonic process chain from modeling to system production – from basic physics to ready-to-use prototypes.
Depending on the area of application, the Fraunhofer IOF offers individual optical solutions. In the area of quantum communication, this ranges from space-capable high-performance sources for entangled photons to complete photonic system solutions based on adaptive optics to lightweight telescopes for space and ground systems.
In this context, the Fraunhofer IOF develops high-performance sources for photon pairs with the broadest possible wavelength spread and wavelengths from the infrared to the ultraviolet range. The system solutions open up new fields of application in low-light imaging as well as previously unexplored wavelength ranges and expand the portfolio of microscopic and telescopic imaging methods.
The Quantum Photonics Research Group of the IOF heads the Fraunhofer flagship project QUILT for quantum imaging and is one the founding members of the Thuringian Center for Quantum Optics and Sensors – InQuoSens.
Friedrich Schiller Universität Jena (FSU)
Due to its centuries-old tradition in optics, the Friedrich-Schiller-Universität Jena (FSU) focuses on photonics, especially at its interfaculty center, the Abbe Center of Photonics (ACP). ACP hosts the research and educational activities on optics and photonics of the university and incorporates important contributions from the non-university optical research institutes and the photonics industry of Jena. It shapes the future of photonics by acting as a leading partner in several joint research and education projects of national and international priority.
ACP's research covers fundamental and applied topics and generates more than 450 publications annually in international peer reviewed journals. The main aim, however, is to achieve synergy effects between the research institutes of the ACP, their industrial partners, and their numerous international collaborators in order to enable scientific and economic added-value.
The quantum research group involved in the FastGhost project is part of the Institute for Applied Physics at FSU, which is embedded in the ACP. It has extensive expertise in nonlinear optics, the generation of photon pairs, and the control of light propagation through nanostructured media.
Of particular importance to the project are the skills to design and implement sources of photon pairs with tailor-made properties as well as the expertise to characterize the generated quantum states of light in all aspects. In addition, FSU researchers have experience with all aspects of experimental optics, e.g., the implementation, alignment, control, and optimization of complex optical setups for quantum imaging and sensing of complex photonic structures.

KTH Royal Institute of Technology (KTH)
The KTH Royal Institute of Technology (KTH) is Sweden's largest and oldest technical university. It plays a central role in Swedish research and is active in a large number of European and international collaborations.
KTH has a state-of-the-art clean room for nanofabrication, device processing and characterization, featuring a new electron beam lithography system, thin film deposition and evaporation facilities, and etching systems, in particular a dedicated sputtering system for NbTiN and NbN can provide very high quality thin films for the fabrication of superconducting detectors. The KTH quantum optics laboratory consists of six experimental setups built around four cryostats. In particular, a Bluefors dilution cryostat enables optical measurements down to 10 mK and an attocube system with a photonic probe station specially designed for long term measurements with high stability.
Our experimental setups are complemented with tunable cw lasers, two wavelength and pulse length tunable OPO lasers addressing the relevant wavelength regions (80 MHz and 320 MHz), self-built low-loss transmission spectrometers, and NIR and IR superconducting single photon detectors. We also have several experimental setups for Tc measurements and for testing superconducting single photon detectors.
