Failure of Bell's Theorem and the Local Causality of the Entangled Photons

Physicist Joy Christian has had a string of papers recently at arXiv (well, I see now that he has been putting his position in print for a few years) in which he argues that "quantum non-locality" is actually an illusion.

His argument is hard to follow (even by other physicists, it seems) but he talk of an topological error and (to quote from an earlier abstract):

When topologies are correctly identified, local-realistic completion of any arbitrary entangled state is always guaranteed in our framework. This vindicates EPR, and entails that quantum entanglement is best understood as an illusion.

To put it another way, as the paper linked to at the top of this article says:

One of the first steps we often take towards measuring a physical quantity is to set up a Cartesian coordinate system {x, y, z} in the Euclidean space E3. This amounts to modeling the Euclidean space as a 3-fold product of the real line, IR3. This procedure has become so familiar to us that in practice we often identify E3 with its Cartesian model, and simply think of IR3 as the Euclidean space.

As we shall see, however, this seemingly innocuous act of convenience comes with a very heavy price: It is largely responsible for the illusions of “quantum non-locality.” Once a coordinate-free geometric model of the Euclidean space is used, the correlations observed in the EPR-type experiments involving photon pairs ... are easily understood, in a strictly local-realistic terms.

Well, it's not clear to me what this means, but my hunch is that if he might be onto something.

There's not too much about him on the web, but there is a bit of a bio here (and proof that he is a "he", not a she.)

Getting rid of quantum non-locality sounds a good way to make the world more aligned with common sense, but maybe Christian's ideas have their own form of counter-intuitiveness as well. (If only I could understand his explanation of the topological issue.)
