Hello to all,
By simulating an EPR type experiment with free photons, I get different
results between QM and a simple local model using just Malus' law.
I would like to know what needs to be done to make both models
produce an identical result.
Here is an image of the simulated experiment.
S1 and S2 are two pulsed single photon sources.
RP is a rotating linear polarizer (fixed on a motor).
By simulating random delays between each emission, the two emitted
photons arrive with an identical but random polarization on the
Alice and Bob polarizers.
In this experiment, the simulation seeks the minimum value that
can be obtained with Eberhard's inequality using perfect
detection.
With QM using the joint probability of the outcomes and zero
entanglement, I get a minimal J/N value close to 0.
With the local model using the Malus law, the minimum value
is around 0.14
Note that if the RP engine is stopped, the local simulation gives the QM result with J/N close to 0.
I would like to know if QM is applicable for this experiment, or
if it is my local model that is incorrect.
How to take into account with QM the fact that the input
polarization is random. ?
Thank you for your answers.
Pierre
