Welcome to the website of the Neutron Interferometer group of the Atominstitut – TU Wien (Vienna, Austria), part of the Neutron- and Quantum Physics group. The dual nature of neutrons – in some respect a particle, in other respect a wave – is manifested by highly counterintuitive effects observed in neutron interferometry, which we apply to  explore foundations of quantum mechanics. We are an experimental group and our main scientific interests are devotes to fundamental topics in quantum mechanics such as, quantum entanglement, weak measurements, uncertainty relations and topological phases.
