Violation of Heisenberg's error-disturbance uncertainty relation in neutron spin measurements
Georg Sulyok, Stephan Sponar, Jacqueline Erhart +3
In its original formulation, Heisenberg's uncertainty principle dealt with the relationship between the error of a quantum measurement and the thereby induced disturbance on the me…
Response to `Comment on "Experimental demonstration of a universally valid error-disturbance uncertainty relation in spin measurements" '
Jacqueline Erhart, Stephan Sponar, Georg Sulyok +3
Here, we reply to the comment by Y. Kurihara. We show that the argument by the author is on an improper basis and thus disagree with his opinion.
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…
Engineering of triply entangled states in a single-neutron system
Yuji Hasegawa, Rudolf Loidl, Gerald Badurek +2
We implemented a triply entangled Greenberger-Horne-Zeilinger(GHZ)-like state and coherently manipulated the spin, path, and energy degrees of freedom in a single neutron system. T…
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…
Violation of Bell-like Inequality for spin-energy entanglement in neutron polarimetry
S. Sponar, J. Klepp, C. Zeiner +2
Violation of a Bell-like inequality for a spin-energy entangled neutron state has been confirmed in a polarimetric experiment. The proposed inequality, in Clauser-Horne-Shimony-Hol…
