Comment on "Energy Non-Conservation in Quantum Mechanics"
Johann Summhammer
In the posting arXiv:2101.11052v2 an experimental protocol involving two spins is proposed, which should show violation of energy conservation in a quantum experiment. In the prese…
Interferometry with Two Pairs of Spin Correlated Photons
Mladen Pavicic, Johann Summhammer
We propose a new experiment employing two independent sources of spin correlated photon pairs. Two photons from different unpolarized sources each pass through a polarizer to a det…
Reconstruction of the spin state
Z. Hradil, J. Summhammer, G. Badurek +1
System of 1/2 spin particles is observed repeatedly using Stern-Gerlach apparatuses with rotated orientations. Synthesis of such non-commuting observables is analyzed using maximum…
Experiment on Interaction-Free Measurement in Neutron Interferometry
Meinrad Hafner, Johann Summhammer
A neutron interferometric test of interaction-free detection of the presence of an absorbing object in one arm of a neutron interferometer has been performed. Despite deviations fr…
Interaction-Free Preparation
G. Krenn, J. Summhammer, K. Svozil
We demonstrate that the preparation of a very well localized atom beam is possible without physical interaction. The preparation is based on the selection of an adequate ensemble o…
