Researchers at RMIT University and other Australian institutions, as well as at the University of Cologne in Germany, have developed a genetic algorithm to confirm the rejection of classical ideas of causality.
The researchers used genetic programming to automatically find the closest classical models for the data, enabling them to map out many dimensions of departure from classical mechanics that quantum correlations exhibit.
"We've lightheartedly called the region mapped out by the algorithm the 'edge of reality,' referring to the common terminology 'local realism' for a model of physics satisfying Einstein's relativity," says University of Technology Sydney researcher Chris Ferrie.
The algorithm works by building causal models through simulated evolution imitating natural selection.
The researchers used photons to generate the quantum correlations that cannot be described using classical mechanics.
