Royal Institute of Technology (KTH)
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.
Dr. Stephan Steinhauer (Postdoctoral Researcher, male, first-time participant to FET) Stephan Steinhauer received his PhD from TU Vienna in 2014 after completing his thesis on metal oxide nanowire devices and their heterogeneous CMOS integration. Before joining KTH at the end of 2017, Stephan was working as Postdoctoral Fellow at the Okinawa Institute of Science and Technology OIST, Japan, supported by a fellowship of the Japan Society for the Promotion of Science. His current research focuses on nanofabrication and materials science-related aspects of quantum technologies, as well as on fundamental properties of excitons in metal oxide semiconductors.
