Three-Path Quantum Cheshire Cat Observed in Neutron Interferometry
Armin Danner, Niels Geerits, Hartmut Lemmel +3
The paradoxical phenomenon of the quantum Cheshire Cat (qCC) refers to situations where different properties of a particle appear to be localised in different paths of an interfero…
Quantifying the presence of a neutron in the paths of an interferometer
Hartmut Lemmel, Niels Geerits, Armin Danner +3
It is commonly assumed that no accurate experimental information can be obtained on the path taken by a particle when quantum interference between the paths is observed. However, r…
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…
Neutron optical test of completeness of quantum root-mean-square errors
Stephan Sponar, Armin Danner, Masanao Ozawa +1
One of the major problems in quantum physics has been to generalize the classical root-mean-square error to quantum measurements to obtain an error measure satisfying both soundnes…
Experimental Test of Entropic Noise-Disturbance Uncertainty Relations for Three-Outcome Qubit Measurements
Stephan Sponar, Armin Danner, Vito Pecile +3
Information-theoretic uncertainty relations formulate the joint immeasurability of two non-commuting observables in terms of information entropies. The trade-off of the accuracy in…
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…
