the arrival of the light quanta

The principle of Mach-Zehnder interferometer shown in this diagram is explained in more detail in the text below.  It can also perform well with photons with matter waves.

At first glance absurd, yet this situation occurs in our real world as recently shown in an international team of researchers who published in Nature Communications , the results of an experiment they conducted with beams neutrons available at Institut Laue-Langevin (ILL) in Grenoble.

The Mach-Zehnder interferometer is operated with the conventional light . Its two blades semitransparent and two are used mirrors for experiments illustrating the principles of quantum physics. With the best known of them, a first blade separates a beam of light into two beams that follow separate one does reflect off two mirrors so that they finally recombine on the second blade paths, as shown in the diagram above. Two detectors can then record the light.

With photons and the two paths are of equal length, the detector always placed horizontally arrival register while the vertical which is never observed. If one wants to know which way, from the top or the bottom, pass the photons, for example, inserting a third detector, the first two indicate the arrival of the light quanta. Variants of this experiment with the existing production fringes of interference connected to specific physical phenomena.
