I think we can find flight 370 if we have satellite images of the flight. The question is, do we have any such images of the actual flight as it was in progress? It was a clear night. Even if the images are low resolution, as long as the color of the plane is distinguishable from its...
The point is that you do not have the ability to distinguish the paths. Before the photon is absorbed it might be H or V polarization, but the atom in the polarizer that absorbs the photon only absorbs 45degree polarization. Therefore each photon absorbed must project from the mixed H and V...
In principle, the polarizer at 45 degrees will allow all of the +45degree polarized light to pass and all of the -45/+135degree polarized light is absorbed. (I've already stated this above.) So now we all understand how a polarizer works. The point is, the absorption is a measurement. This...
What's up with the "absorptive" quantum eraser?
In the famed "quantum eraser" of physics, there is two distinct types, one type which uses an absorptive apparatus for the method of "unmarking the path" and one which does not. For the absorptive type of quantum eraser we have a clear fallacy in...
