This was a new paper which was in pre-print that I had discussed with Bill S
Original paper:

This has caused a bit of a stir because of the problem it perhaps says something about the concept of a multiverse depending on where you sit with QM. Anton Zeilinger's original work opened a question which many have now taken up.
Here we report an experiment with single photonic qutrits, which provides evidence that no joint probability distribution describing the outcomes of all possible measurements—and, therefore, no non-contextual theory—can exist.
Our results illustrate a deep incompatibility between quantum mechanics and classical physics that cannot in any way result from entanglement.
Probably for the layman look at Sean Carroll's simple 36 slideshow (
http://www.slideshare.net/seanmcarroll/the-many-worlds-of-quantum-mechanics) in particular think about slide 34.
Expect a lot more to be said on this subject because as you would well imagine it upsets many a QM researcher, I am sitting on the fence on the issue as I think the traditional view still holds sway ... more data please ... but I do like controversial post titles
