Photon exchange and entanglement formation during the transmission through a rectangular quantum barrier
Georg Sulyok, Katharina Durstberger-Rennhofer, Johann Summhammer
When a quantum particle traverses a rectangular potential created by a quantum field both photon exchange and entanglement between particle and field take place. We present analyti…
Probing neutron's electric neutrality with Ramsey Spectroscopy of gravitational quantum states of ultra-cold neutrons
Katharina Durstberger-Rennhofer, Tobias Jenke, Hartmut Abele
We propose to test the electric neutrality of neutrons by a new technique using the spectroscopy of quantum states of ultra-cold neutrons in the gravity potential above a vertical…
Energy entanglement in neutron interferometry
Katharina Durstberger-Rennhofer, Yuji Hasegawa
Entanglement between degrees of freedom, namely between the spin, path and (total) energy degrees of freedom, for single neutrons is exploited. We implemented a triply entangled Gr…
Kochen-Specker theorem studied with neutron interferometer
Yuji Hasegawa, Katharina Durstberger-Rennhofer, Stephan Sponar +1
The Kochen-Specker theorem theoretically shows evidence of the incompatibility of noncontextual hidden variable theories with quantum mechanics. Quantum contextuality is a more gen…
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…
