Hi, I've just finished reading the article "Reality Bits" in the January 25-31, 2014 edition of New Scientist. These links are introductions for those of you who do not read New Scientist: http://www.newscientist.com/article/...aster-bit.html [Broken] http://arxiv.org/abs/1210.4535 http://en.wikipedia.org/wiki/U-bit Can anybody explain what Dr. Wootters is talking about? I don't think he is reformulating QM with the mere substitution of sqrt(-1) for its matrix identity since that would only yield a notationally equivalent and trivial reformulation and the math would not change. But instead, I think Dr. Wooters has a new approach to avoiding imaginary numbers in QM. At this point I don't have a clue what Dr. Wooters is proposing and any incite would be greately appreciated. EDIT: and some insights would be appreciated too.
