NANOQUESTFIT was dedicated to prepare nanoparticles in highly non-classical quantum states and utilize them to test the linearity of quantum physics over mesoscopic distances and time scales in a mass range that has remained hitherto unexplored. This goal was realized in an interdisciplinary effort of European experts in quantum optics, nanotechnology, chemistry, and cluster physics. NANOQUESTFIT lays the scientific ground for a better understanding of practical and fundamental limits of future quantum technologies and will generate the basis for new quantum-enhanced sensing devices with matter waves composed of atoms, molecules and nanoparticles.  

Project partners:

QuNaBioS, Quantum Phenomena and Nanoscale Biological Systems

This project was a joint venture between the Quantum Nanobiology Team (QNB) of Alipasha Vaziri and the Quantum Nanophysics Team (QNP) of Markus Arndt. It was selected by the University of Vienna to enable high-risk/high-gain research in the largely unexplored and interdisciplinary scientific territory between the two fields. The project was completed with the call of Dr. Vaziri on a Professorship at Rockefeller University, New York.

Wittgenstein Prize, FWF

In 2008 Markus Arndt received the Wittgenstein Award of the Ministry of Science and the Austrian Science Funds FWF for his research in Quantum Nanophysics. The programme was  successfully completed in December 2013. 

ESF CRP MIME: Molecule Interferometry and Metrology

MIME united groups from Switzerland, Germany, Austria and the UK in a joint effort in exploring the new field of quantum assisted molecule metrology.

Coordinator: Prof. Markus Arndt, University of Vienna

Project partners: 

  • Prof. Klaus Hornberger, now Univ. Duisburg Essen,
  • Prof. Horst Hahn / Prof. Herbert Gleiter, KIT Karlsruhe,
  • Prof. Marcel Mayor, University of Basel,
  • Dr. Hendrik Ulbricht, University of Southampton (now Professor there) 

FWF START Prize 2001-2008

In 2001 Markus Arndt received the FWF START Prize for his research on molecule diffraction. The programme was  successfully evaluated and extended in 2004. It was successfully completed in 2008.
