An analysis of the energy exchange by photons is presented based on single-photon Gedanken experiments and the Heisenberg uncertainty principle. Excluding hidden variable properties of a single photon one has to accept that the total photon trajectory undergoes causal influences from the final state separated in time and space from the initial stat...

... argumentation leading to evidence for the nontemporal character of a single photon is not trivial and requires a series of argumentations with side-branches and direct as well as indirect proofs, see the flow-chart of Fig. 2. Central in the discussion are a series of Gedanken-experiments with single photons. In the case of linear optics this is not a real restriction as in that case, by definition, there is no interaction between photons. In order to arrive at meaningful results all experiments are repeated sufficiently so that statistical noise can be ...
Context 2
... having gone through the branches of the argumentations outlined in Fig. 2 the conclusion becomes obvious: in the case of energy-exchange by photons nontemporal processes play a decisive role. In the special case that one considers photons as objects of reality evidence is given that the coherence length is unchanged along the photon trajectory and is determined by the fundamental time uncertainty in the ...

This article shows, Synge-Weber's classical problem statement about two particles interacting by a signal can be reduced to the case where the same particle is located in two different points A and B of the basic space-time in the same moment of time, so the states A and B are entangled. This particle, being actual two particles in the entangled st...
We propose a resource-efficient error-rejecting entangled-state analyzer for polarization-encoded multiphoton systems. The analyzer works in a passive way and can completely distinguish $2^n$ Greenberger-Horne-Zeilinger~(GHZ) states of $n$ photons without using any active operation or fast switching. The efficiency and fidelity of the GHZ-state ana...

The measured LLR return signals fit to measurements to the bear surface of the Moon and not to retroreflectors. -----------------
This paper provides an overview of the Lunar Laser Ranging (LLR) experiments. The measurement principle is explained and its theory is derived. Both contributions, the direct reflected light from ret...
The measurement of quantum states is one of the most important problems in quantum mechanics. We introduce a quantum state tomography technique in which the state of a qubit is reconstructed, while the qubit remains undetected. The key ingredients are: (i) employing an additional qubit, (ii) aligning the undetected qubit with a known reference stat...
We describe a new technique of quantum astrometry, which potentially can improve the resolution of optical interferometers by orders of magnitude. The approach requires fast imaging of single photons with sub-nanosecond resolution, greatly benefiting from recent advances in photodetection technologies. We also describe results of first proof of pri...
