Java simulation available

Chantal Roth has created a very nice Java implementation of the EPR experiment for testing purposes. In her own words:

"A simple 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 between the measurements at the detectors based for each angle between the filters. The GUI allows a user to enter a formula to compute the probability if a detection of a particle happens or not, which is then compiled on the fly."

The application can be downloaded at Sourceforge:

To run it, you need the Java JDK and NetBeans IDE 7. This can be downloaded in one package at:

Rewrite of reference simulation

Recently I can enjoy some hits from an article with criticism on the work of Joy Christian from Sascha Vongehr. While it is true that the ideas of Joy contradicts mainstream physics, his arguments seems sound, but the arguments of Sascha for criticizing this work are mostly hand waving and of low scientific value.

But apart from that the challenge from Sascha (however sarcastically stated) is the same as in this blog: if a LHV model is possible, it can be demonstrated and proved by an open source program.

The reference application for these simulations, based on the work of DeRaedt, has now been completely rewritten. The classes that implements a simulation have been separated. Adding a new type of simulation can be done easily by copying a folder with classes from another simulationtype and change their implementation.

The classes mostly represents the real objects that are involved in a typical EPR experiment. A special feature in this release is the availability of a libary with classes for Geometric Algebra, as they are generated for C-sharp by Gaigen. As always, the program can be downloaded at sourceforge
