On the Impossibility to Extend Triples of Mutually Unbiased Product
Bases in Dimension Six [PDF]
Daniel McNulty, Stefan WeigertAn analytic proof is given which shows that it is impossible to extend any triple of mutually unbiased product bases in dimension six by a single mutually unbiased vector. The approach improves on recent computer-aided methods to derive this result, and it represents one of the few analytic forays into the properties of mutually unbiased bases for d=6.View original: http://arxiv.org/abs/1203.6887
