Usual quantum nonsense from physicists pretending that light, when sent through a double slit, is sometimes observed to be a photon and other times as a wave. It isn’t ever actually observed even directly to be a photon. That is a false assumption. Seeing as no one can actually see a photon as it hits the photodetector plane. All we see is a readout on a screen of wave light incident on the photodetector. And that wave radiation being Quantised into pulses by the detector atoms and delivered to the ‘electron cascade’ of the circuit. And then relayed to the computer screen as dots forming an interference pattern. The interference pattern created by the dots is simply a readout of the intensity of wave only incident radiation on the detector screen. At any point on the screen where there is more light due to the interference pattern at the detector screen, there will be more incident wave radiation. And more of these quantised dots. And where less light at other points in the interference pattern due to lower intensity of light at that point on the detector plane, there will be fewer dots on the readout screen. No quantum wave particle duality is needed to explain both the dots and the interference pattern.
That is unless one is a QT theorists who is fantasising they actually saw a photon and saw a collection of these imaginary photons arrange themselves magically into an interference pattern. In fact, All they actually saw was an amplified second generation image of wave only light being quantised at and by the photodetector atoms. Then amplified electronically and delivered via software and pc screens as an interference pattern to the quantum theorists eyes by the pc screen.
But to deal specifically with the fantasy included in the above cited paper:
What is creating the coherent light in the experiment?
It is the the array of atoms held in a lattice and reflecting the incident laser. Only coherent light when split into two or more coherent sources at a “slit” can create interference patterns when incident on the detector plane.
What is creating the incoherent light in the experiment?
It is the atoms moving randomly, and reflecting or re-emitting the now incoherent light onto the detector screen. At which point no interference is noted. As Young noticed in his classic interference experiments.
Because, as any one with a basic grasp of physics knows, an incoherent light source cannot produce interference patterns. And thus in the experiment only the atoms held together in a lattice and reflecting or re-emitting as multiple coherent light sources can interference patterns be produced. As observed in the paper cited above.
In their attempts to pretend they have supplied further proof of the quantum nature of light, the authors of the paper have forgotten basic physics. In that a classical model can fully explain their experimental results. In that in a wave only classical model, a classical wave only incoherent light source will not produce any interference at the detector plane. And will only do so only if the multi atom incoherent light source is artificially constrained into a lattice of multiple coherent light sources that then can produce interference. As fully explained elsewhere here on this blog.
