Let’s use a disc throwning system, where two porcelain plates are thrown at once and in different directions, one with its axis horizontal and the other vertical. To catch the plates we use a detector, made of a foam plate with parallel slots, in which the plates remain stuck. The structured foam plates are designed so well that they catch even plates with a spatial deviation of +/-45° if the plate comes perfectly centric to the slit. To the right and to the left from this point the probability reduces until it will be zero for a plate, hitting the foam detectetor in the center of the area between the slits.
Unfortunately the engineers made a joke and rotate synchronously the two mechanism for the throwing. Still the plates stay entangled. The outcomming plate 1 could be thrown in any angle and the plate 2 will be thrown by the angle of the first plate plus 90°.
For me the measurable results with the two foam plates are the same as for two optical filters and two photons from spontaneous parametric down-conversion. Noting the results of the measurements, could one see a difference between the two experiments?
In my view the results of the mechanical system with the two detectors perpendicular to each other will be:
- in 25% of the measurement both detectors catch a plate
- in 25% the left detector only will catch a plate
- in 25% the same happens with the right detector an
- in 25% no one detector catches a plate.
