Lecture 1

Lecture 2

The simplest quantum property demonstration I have ever seen is copied from Lecture #2.  Thinking classically you would conclude that the photo would exit vertically 50% of the time and to the right 50% of the time.  But it always exits to the right. If I understand correctly for the simplest experiment you would not even need a single phone detector / counter. You could just see you get output to the right and zero in the vertical directly of the second 1/2 silvered mirror.   You can also place a barrier in the upper horizontal path and that causes 1/2 the photons to exit vertical and 1/2 to exit to the right.  

In practice the system is arranged so it can us a single beam splitter plate as follows.
