Scientific Goals of NANOQUESTFIT


Quantum phenomena are an important basis for future information technologies. They will become relevant for quantum-enhanced metrology and advanced sensors, which exploit the quantum superposition principle at a mesoscopic scale.

The NANOQUESTFIT consortium will 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 unexplored, hitherto.

This goal will be realized in an interdisciplinary effort of European experts in quantum optics, nanotechnology, chemistry, and cluster physics.

NANOQUESTFIT will realize novel quantum optical elements, quantum coherence and interference studies with objects up to and beyond 105 atomic mass units, for the first time.

New beam methods will be explored for tailor-made nanoparticles between 104 and 107 atomic mass units.
Decoherence is the enemy of many future quantum-based technologies. Our NANOQUESTFIT consortium will therefore investigate environmental decoherence with objects in a complexity class that is expected to become relevant in future quantum devices.
Advanced experiments in NANOQUESTFIT will allow defining new constraints on unconventional extensions of quantum theory, which will be explored and elaborated on with regard to their conceptional consistency.  


NANOQUESTFIT works at the cutting edge of modern science to lay the scientific ground for a better understanding of practical and fundamental limits of future quantum technologies.

It will also generate spin-offs for new quantum-enhanced sensing devices: the beam splitter technologies developed in NANOQUESTFIT shall be applicable to a wide range of matter waves composed of atoms, molecules and nanoparticles.
