  Example... "Young's double slit experiment"
http://en.wikipedia.org/wiki/Double-slit_experiment  The classical wave
explanation gives the characteristic interference fringes as per...

Quantum mechanics gives the same output, but uses an extremely ugly
probability equation the get the result.  So what happens when you have
an extremely weak light source such that only one photon is present in
the device at any time?  Surely it won't have anything to interfere with
and cause a diffraction pattern?  Wrong.  The exact same interference
fringe pattern shows up, although it obviously takes longer for the
photographic film to expose.  This effect even works when sending
electrons 1-at-a-time through a double slit filter (Taylor's Experiment)
