Direct experimental test of commutation relation via weak value
Richard Wagner, Wenzel Kersten, Armin Danner +3
The canonical commutation relation is the hallmark of quantum theory and Heisenberg's uncertainty relation is a direct consequence of it. But despite its fundamental role in quantu…

Experimental Test of Tight State-Independent Preparation Uncertainty Relations for Qubits
Stephan Sponar, Armin Danner, Kazuma Obigane +2
The well-known Robertson-Schroedinger uncertainty relations miss an irreducible lower bound. This is widely attributed to the lower bound's state-dependence. Therefore, Abbott \emp…

Spin - Rotation Coupling Observed in Neutron Interferometry
Armin Danner, Bülent Demirel, Wenzel Kersten +4
Einstein's theory of general relativity and quantum theory form the two major pillars of modern physics. However, certain inertial properties of a particle's intrinsic spin are inc…
