Fundamental phenomena of quantum mechanics explored with neutron interferometers
J. Klepp, S. Sponar, Y. Hasegawa
Ongoing fascination with quantum mechanics keeps driving the development of the wide field of quantum-optics, including its neutron-optics branch. Application of neutron-optical me…
New Aspects of Geometric Phases in Experiments with polarized Neutrons
S. Sponar, J. Klepp, K. Durstberger-Rennhofer +7
Geometric phase phenomena in single neutrons have been observed in polarimeter and interferometer experiments. Interacting with static and time dependent magnetic fields, the state…
Geometric Phase in Entangled Systems: A Single-Neutron Interferometer Experiment
S. Sponar, J. Klepp, R. Loidl +6
The influence of the geometric phase on a Bell measurement, as proposed by Bertlmann et al. in [Phys. Rev. A 69, 032112 (2004)], and expressed by the Clauser-Horne-Shimony-Holt (CH…
Experimental test of quantum contextuality in neutron interferometry
H. Bartosik, J. Klepp, C. Schmitzer +4
We performed an experimental test of the Kochen-Specker theorem based on an inequality derived from the Peres-Mermin proof, using spin-path (momentum) entanglement in a single neut…
Experimental demonstration of the stability of Berry's phase for a spin-1/2 particle
S. Filipp, J. Klepp, Y. Hasegawa +4
The geometric phase has been proposed as a candidate for noise resilient coherent manipulation of fragile quantum systems. Since it is determined only by the path of the quantum st…
Observation of nonadditive mixed state phases with polarized neutrons
J. Klepp, S. Sponar, S. Filipp +3
In a neutron polarimetry experiment the mixed state relative phases between spin eigenstates are determined from the maxima and minima of measured intensity oscillations. We consid…
