Theory Update 20

The link between non locality and quantum uncertainty has been in the news lately, following recent work of Wehner and Oppenheim. Another paper by Wehner talks about cool gadgets like our friendly MUBs and Latin squares, which are created from the digits $1$ to $n$. The two orthogonal squares of size $3$ are

which we recognise as the circulant matrices underlying the Koide formula, amongst other things. Orthogonality means that all nine ordered pairs are distinct. In fact, these are the two-qutrit path sets, from which Koide phases are derived.
