That the left photon moves towards the left and is polarised in the horizontal plane .
That the right photon moves towards the right and is also polarised in the horizontal plane .
The idea behind this experiment is to test the sequence of events when you insert a two channel polariser in the left beam
and you leave the right beam undisturbed with the aid of a Coincidence Monitor.
The result of the test will be 2 sequence of events, showing the arrival times of the photons.
Counter 1: x x x x x x x x x tn1 = 9
Counter 3: x x x x x x x x x x tn3 = 10
Counter 2: x x x x x x x x x x x x x x x x x x tn2 = 18
The above pattern shows no difference for the right beam (counter 2)
In total 20 photon pairs are created and 2 are missing.
For the left beam there is a clear difference.
Approximately 50% goes to counter in the + direction and almost 50% goes to counter 3 in the - direction.
At 2 occasions nothing is counted and at one occasion a photon is counted at both counters.
