Does quantum entanglement imply free will?

[Jim__]

Excerpt

Today, Jonathan Barrett from the University of Bristol and Nicolas Gisin from the University of Geneva provide us with an interesting new take on this problem. They assume that entanglement does occur as quantum mechanics proscribes and then ask how much free will an experimenter must have to rule out the possibility of hidden interference.

The answer is curious. Barret and Gisin prove that if there is any information shared by the experimenters and the particles they are to measure, then entanglement can be explained by some kind of hidden process that is deterministic.

In practical terms, this means that there can be no shared information between the random number generators that determine the parameters of the experiments to be made, and the particles to be measured.

But the same also holds true for the experimenters themselves. It means there can be no information shared between them and the particles to be measured either. In other words, they must have completely free will.
