TU Wien

Description of the Institution

The TU Wien, with 27.000 students and 4.500 employees, is the largest technology-oriented university in Austria. It was founded 1815 and has a long-standing tradition of academic and cultural success with alumni such as Christian Doppler, Joseph Loschmidt, Otto Wagner, and Johann Strauss. Today, it is among the top universities in Europe, currently hosting 14 ERC grants (7 in physics). TU Wien offers 53 programs of study in 8 departments. The physics department is subdivided into 4 institutes, the Atominstitut (ATI) being the largest one. It holds a long tradition in quantum physics, demonstrating, e.g., the first neutron interferometer in 1974. Today, the ATI hosts a variety of research groups centered around nuclear and atomic physics with a strong emphasis on quantum optics, laser spectroscopy, and metrology.

The larger scientific environment in Vienna also comprises the University of Vienna and the Austrian Academy of Sciences’ Institute for Quantum Optics and Quantum Information with an impressive number of high-profile groups in quantum physics and quantum optics. Many groups, including the group of the PI, are part of the faculty of the Vienna Doctoral Program on Complex Quantum Systems which attracts excellent students from all over the world to join quantum physics research in Vienna.


Description of Main Tasks and Participant’s Profile

ATI has a wide expertise in coupling molecules in solids and solid-state quantum emitters to optical nanofibers. It was the first group that has successfully shown that photostable single molecules in organic nanocrystals can be grown, which represents a crucial step for interfacing such quantum emitters with nanophotonic platforms and hence is a prerequisite for any on-chip system based on these quantum emitters. ATI will therefore heavily contribute in implementing single-photon nonlinearities on waveguide chips. At ATI, we have more than ten years of experience in cryogenics – an environment necessary for the proposed molecular emitters and also most other solid-state quantum emitters. It will assist UBER with this expertise and also experimentally study novel quantum emitters, for example, based on 2D materials. ATI will also work together closely with FBH to develop an on-chip design suitable for cryogenic temperatures.
