Summary

A Java simulation of a typical EPR experiment by creating "entangled" particles that are sent to two detectors A and B. After many such experiments the statistics are computed, including the CHSH value and also the correlation for each angle. (see docs for a screen shot)

You can easily to add your own model if you want to attempt to break the CHSH inequality, by adding a class to: Simulation\src\org\physics\epr\hiddenvars

And by changing the class used in the main class: Simulation\src\org\physics\epr\gui\SimulationTopComponent

The current version is able to break it - but only by allowing non-detection:

See in the formula class: if (Math.random()<=pdetect) return spin; else return Integer.MIN_VALUE;

By allowing the non-detection of certain particles, the CHSH inequality can be broken.

I would claim that this is the only way to break it... ;-)
